 # Contributing guide
 Things you'll need:
 - To create [Pull Requests](https://forgejo.org/docs/latest/user/pull-requests-and-git-flow/), you will need to register your [pub.solar ID](https://auth.pub.solar) first.
 - For small changes, e.g. to documentation, you can directly edit files in the browser.
 ### Getting a development shell
 First, get a local copy of this repository:
 ```
 git clone https://git.pub.solar/pub-solar/infra.git
 cd infra
 ```
 then, install [the package manager nix](https://nixos.org/download).
 Finally, run:
 ```
 nix develop
 ```
 This will install a development shell (devshell) with all required tools.
 ### Final checks before creating a Pull Request
 Before creating a pull request, it's recommended to check the formatting:
 ```
 treefmt
 ```
 If you are a terminal-lover, the [AGit alternative](https://forgejo.org/docs/latest/user/agit-support/) to the web based Pull Request workflow might be interesting.

 ### GNU AFFERO GENERAL PUBLIC LICENSE
 Version 3, 19 November 2007
 Copyright (C) 2007 Free Software Foundation, Inc.
 <https://fsf.org/>
 Everyone is permitted to copy and distribute verbatim copies of this
 license document, but changing it is not allowed.
 ### Preamble
 The GNU Affero General Public License is a free, copyleft license for
 software and other kinds of works, specifically designed to ensure
 cooperation with the community in the case of network server software.
 The licenses for most software and other practical works are designed
 to take away your freedom to share and change the works. By contrast,
 our General Public Licenses are intended to guarantee your freedom to
 share and change all versions of a program--to make sure it remains
 free software for all its users.
 When we speak of free software, we are referring to freedom, not
 price. Our General Public Licenses are designed to make sure that you
 have the freedom to distribute copies of free software (and charge for
 them if you wish), that you receive source code or can get it if you
 want it, that you can change the software or use pieces of it in new
 free programs, and that you know you can do these things.
 Developers that use our General Public Licenses protect your rights
 with two steps: (1) assert copyright on the software, and (2) offer
 you this License which gives you legal permission to copy, distribute
 and/or modify the software.
 A secondary benefit of defending all users' freedom is that
 improvements made in alternate versions of the program, if they
 receive widespread use, become available for other developers to
 incorporate. Many developers of free software are heartened and
 encouraged by the resulting cooperation. However, in the case of
 software used on network servers, this result may fail to come about.
 The GNU General Public License permits making a modified version and
 letting the public access it on a server without ever releasing its
 source code to the public.
 The GNU Affero General Public License is designed specifically to
 ensure that, in such cases, the modified source code becomes available
 to the community. It requires the operator of a network server to
 provide the source code of the modified version running there to the
 users of that server. Therefore, public use of a modified version, on
 a publicly accessible server, gives the public access to the source
 code of the modified version.
 An older license, called the Affero General Public License and
 published by Affero, was designed to accomplish similar goals. This is
 a different license, not a version of the Affero GPL, but Affero has
 released a new version of the Affero GPL which permits relicensing
 under this license.
 The precise terms and conditions for copying, distribution and
 modification follow.
 ### TERMS AND CONDITIONS
 #### 0. Definitions.
 "This License" refers to version 3 of the GNU Affero General Public
 License.
 "Copyright" also means copyright-like laws that apply to other kinds
 of works, such as semiconductor masks.
 "The Program" refers to any copyrightable work licensed under this
 License. Each licensee is addressed as "you". "Licensees" and
 "recipients" may be individuals or organizations.
 To "modify" a work means to copy from or adapt all or part of the work
 in a fashion requiring copyright permission, other than the making of
 an exact copy. The resulting work is called a "modified version" of
 the earlier work or a work "based on" the earlier work.
 A "covered work" means either the unmodified Program or a work based
 on the Program.
 To "propagate" a work means to do anything with it that, without
 permission, would make you directly or secondarily liable for
 infringement under applicable copyright law, except executing it on a
 computer or modifying a private copy. Propagation includes copying,
 distribution (with or without modification), making available to the
 public, and in some countries other activities as well.
 To "convey" a work means any kind of propagation that enables other
 parties to make or receive copies. Mere interaction with a user
 through a computer network, with no transfer of a copy, is not
 conveying.
 An interactive user interface displays "Appropriate Legal Notices" to
 the extent that it includes a convenient and prominently visible
 feature that (1) displays an appropriate copyright notice, and (2)
 tells the user that there is no warranty for the work (except to the
 extent that warranties are provided), that licensees may convey the
 work under this License, and how to view a copy of this License. If
 the interface presents a list of user commands or options, such as a
 menu, a prominent item in the list meets this criterion.
 #### 1. Source Code.
 The "source code" for a work means the preferred form of the work for
 making modifications to it. "Object code" means any non-source form of
 a work.
 A "Standard Interface" means an interface that either is an official
 standard defined by a recognized standards body, or, in the case of
 interfaces specified for a particular programming language, one that
 is widely used among developers working in that language.
 The "System Libraries" of an executable work include anything, other
 than the work as a whole, that (a) is included in the normal form of
 packaging a Major Component, but which is not part of that Major
 Component, and (b) serves only to enable use of the work with that
 Major Component, or to implement a Standard Interface for which an
 implementation is available to the public in source code form. A
 "Major Component", in this context, means a major essential component
 (kernel, window system, and so on) of the specific operating system
 (if any) on which the executable work runs, or a compiler used to
 produce the work, or an object code interpreter used to run it.
 The "Corresponding Source" for a work in object code form means all
 the source code needed to generate, install, and (for an executable
 work) run the object code and to modify the work, including scripts to
 control those activities. However, it does not include the work's
 System Libraries, or general-purpose tools or generally available free
 programs which are used unmodified in performing those activities but
 which are not part of the work. For example, Corresponding Source
 includes interface definition files associated with source files for
 the work, and the source code for shared libraries and dynamically
 linked subprograms that the work is specifically designed to require,
 such as by intimate data communication or control flow between those
 subprograms and other parts of the work.
 The Corresponding Source need not include anything that users can
 regenerate automatically from other parts of the Corresponding Source.
 The Corresponding Source for a work in source code form is that same
 work.
 #### 2. Basic Permissions.
 All rights granted under this License are granted for the term of
 copyright on the Program, and are irrevocable provided the stated
 conditions are met. This License explicitly affirms your unlimited
 permission to run the unmodified Program. The output from running a
 covered work is covered by this License only if the output, given its
 content, constitutes a covered work. This License acknowledges your
 rights of fair use or other equivalent, as provided by copyright law.
 You may make, run and propagate covered works that you do not convey,
 without conditions so long as your license otherwise remains in force.
 You may convey covered works to others for the sole purpose of having
 them make modifications exclusively for you, or provide you with
 facilities for running those works, provided that you comply with the
 terms of this License in conveying all material for which you do not
 control copyright. Those thus making or running the covered works for
 you must do so exclusively on your behalf, under your direction and
 control, on terms that prohibit them from making any copies of your
 copyrighted material outside their relationship with you.
 Conveying under any other circumstances is permitted solely under the
 conditions stated below. Sublicensing is not allowed; section 10 makes
 it unnecessary.
 #### 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
 No covered work shall be deemed part of an effective technological
 measure under any applicable law fulfilling obligations under article
 11 of the WIPO copyright treaty adopted on 20 December 1996, or
 similar laws prohibiting or restricting circumvention of such
 measures.
 When you convey a covered work, you waive any legal power to forbid
 circumvention of technological measures to the extent such
 circumvention is effected by exercising rights under this License with
 respect to the covered work, and you disclaim any intention to limit
 operation or modification of the work as a means of enforcing, against
 the work's users, your or third parties' legal rights to forbid
 circumvention of technological measures.
 #### 4. Conveying Verbatim Copies.
 You may convey verbatim copies of the Program's source code as you
 receive it, in any medium, provided that you conspicuously and
 appropriately publish on each copy an appropriate copyright notice;
 keep intact all notices stating that this License and any
 non-permissive terms added in accord with section 7 apply to the code;
 keep intact all notices of the absence of any warranty; and give all
 recipients a copy of this License along with the Program.
 You may charge any price or no price for each copy that you convey,
 and you may offer support or warranty protection for a fee.
 #### 5. Conveying Modified Source Versions.
 You may convey a work based on the Program, or the modifications to
 produce it from the Program, in the form of source code under the
 terms of section 4, provided that you also meet all of these
 conditions:
 - a) The work must carry prominent notices stating that you modified
  it, and giving a relevant date.
 - b) The work must carry prominent notices stating that it is
  released under this License and any conditions added under
  section 7. This requirement modifies the requirement in section 4
  to "keep intact all notices".
 - c) You must license the entire work, as a whole, under this
  License to anyone who comes into possession of a copy. This
  License will therefore apply, along with any applicable section 7
  additional terms, to the whole of the work, and all its parts,
  regardless of how they are packaged. This License gives no
  permission to license the work in any other way, but it does not
  invalidate such permission if you have separately received it.
 - d) If the work has interactive user interfaces, each must display
  Appropriate Legal Notices; however, if the Program has interactive
  interfaces that do not display Appropriate Legal Notices, your
  work need not make them do so.
 A compilation of a covered work with other separate and independent
 works, which are not by their nature extensions of the covered work,
 and which are not combined with it such as to form a larger program,
 in or on a volume of a storage or distribution medium, is called an
 "aggregate" if the compilation and its resulting copyright are not
 used to limit the access or legal rights of the compilation's users
 beyond what the individual works permit. Inclusion of a covered work
 in an aggregate does not cause this License to apply to the other
 parts of the aggregate.
 #### 6. Conveying Non-Source Forms.
 You may convey a covered work in object code form under the terms of
 sections 4 and 5, provided that you also convey the machine-readable
 Corresponding Source under the terms of this License, in one of these
 ways:
 - a) Convey the object code in, or embodied in, a physical product
  (including a physical distribution medium), accompanied by the
  Corresponding Source fixed on a durable physical medium
  customarily used for software interchange.
 - b) Convey the object code in, or embodied in, a physical product
  (including a physical distribution medium), accompanied by a
  written offer, valid for at least three years and valid for as
  long as you offer spare parts or customer support for that product
  model, to give anyone who possesses the object code either (1) a
  copy of the Corresponding Source for all the software in the
  product that is covered by this License, on a durable physical
  medium customarily used for software interchange, for a price no
  more than your reasonable cost of physically performing this
  conveying of source, or (2) access to copy the Corresponding
  Source from a network server at no charge.
 - c) Convey individual copies of the object code with a copy of the
  written offer to provide the Corresponding Source. This
  alternative is allowed only occasionally and noncommercially, and
  only if you received the object code with such an offer, in accord
  with subsection 6b.
 - d) Convey the object code by offering access from a designated
  place (gratis or for a charge), and offer equivalent access to the
  Corresponding Source in the same way through the same place at no
  further charge. You need not require recipients to copy the
  Corresponding Source along with the object code. If the place to
  copy the object code is a network server, the Corresponding Source
  may be on a different server (operated by you or a third party)
  that supports equivalent copying facilities, provided you maintain
  clear directions next to the object code saying where to find the
  Corresponding Source. Regardless of what server hosts the
  Corresponding Source, you remain obligated to ensure that it is
  available for as long as needed to satisfy these requirements.
 - e) Convey the object code using peer-to-peer transmission,
  provided you inform other peers where the object code and
  Corresponding Source of the work are being offered to the general
  public at no charge under subsection 6d.
 A separable portion of the object code, whose source code is excluded
 from the Corresponding Source as a System Library, need not be
 included in conveying the object code work.
 A "User Product" is either (1) a "consumer product", which means any
 tangible personal property which is normally used for personal,
 family, or household purposes, or (2) anything designed or sold for
 incorporation into a dwelling. In determining whether a product is a
 consumer product, doubtful cases shall be resolved in favor of
 coverage. For a particular product received by a particular user,
 "normally used" refers to a typical or common use of that class of
 product, regardless of the status of the particular user or of the way
 in which the particular user actually uses, or expects or is expected
 to use, the product. A product is a consumer product regardless of
 whether the product has substantial commercial, industrial or
 non-consumer uses, unless such uses represent the only significant
 mode of use of the product.
 "Installation Information" for a User Product means any methods,
 procedures, authorization keys, or other information required to
 install and execute modified versions of a covered work in that User
 Product from a modified version of its Corresponding Source. The
 information must suffice to ensure that the continued functioning of
 the modified object code is in no case prevented or interfered with
 solely because modification has been made.
 If you convey an object code work under this section in, or with, or
 specifically for use in, a User Product, and the conveying occurs as
 part of a transaction in which the right of possession and use of the
 User Product is transferred to the recipient in perpetuity or for a
 fixed term (regardless of how the transaction is characterized), the
 Corresponding Source conveyed under this section must be accompanied
 by the Installation Information. But this requirement does not apply
 if neither you nor any third party retains the ability to install
 modified object code on the User Product (for example, the work has
 been installed in ROM).
 The requirement to provide Installation Information does not include a
 requirement to continue to provide support service, warranty, or
 updates for a work that has been modified or installed by the
 recipient, or for the User Product in which it has been modified or
 installed. Access to a network may be denied when the modification
 itself materially and adversely affects the operation of the network
 or violates the rules and protocols for communication across the
 network.
 Corresponding Source conveyed, and Installation Information provided,
 in accord with this section must be in a format that is publicly
 documented (and with an implementation available to the public in
 source code form), and must require no special password or key for
 unpacking, reading or copying.
 #### 7. Additional Terms.
 "Additional permissions" are terms that supplement the terms of this
 License by making exceptions from one or more of its conditions.
 Additional permissions that are applicable to the entire Program shall
 be treated as though they were included in this License, to the extent
 that they are valid under applicable law. If additional permissions
 apply only to part of the Program, that part may be used separately
 under those permissions, but the entire Program remains governed by
 this License without regard to the additional permissions.
 When you convey a copy of a covered work, you may at your option
 remove any additional permissions from that copy, or from any part of
 it. (Additional permissions may be written to require their own
 removal in certain cases when you modify the work.) You may place
 additional permissions on material, added by you to a covered work,
 for which you have or can give appropriate copyright permission.
 Notwithstanding any other provision of this License, for material you
 add to a covered work, you may (if authorized by the copyright holders
 of that material) supplement the terms of this License with terms:
 - a) Disclaiming warranty or limiting liability differently from the
  terms of sections 15 and 16 of this License; or
 - b) Requiring preservation of specified reasonable legal notices or
  author attributions in that material or in the Appropriate Legal
  Notices displayed by works containing it; or
 - c) Prohibiting misrepresentation of the origin of that material,
  or requiring that modified versions of such material be marked in
  reasonable ways as different from the original version; or
 - d) Limiting the use for publicity purposes of names of licensors
  or authors of the material; or
 - e) Declining to grant rights under trademark law for use of some
  trade names, trademarks, or service marks; or
 - f) Requiring indemnification of licensors and authors of that
  material by anyone who conveys the material (or modified versions
  of it) with contractual assumptions of liability to the recipient,
  for any liability that these contractual assumptions directly
  impose on those licensors and authors.
 All other non-permissive additional terms are considered "further
 restrictions" within the meaning of section 10. If the Program as you
 received it, or any part of it, contains a notice stating that it is
 governed by this License along with a term that is a further
 restriction, you may remove that term. If a license document contains
 a further restriction but permits relicensing or conveying under this
 License, you may add to a covered work material governed by the terms
 of that license document, provided that the further restriction does
 not survive such relicensing or conveying.
 If you add terms to a covered work in accord with this section, you
 must place, in the relevant source files, a statement of the
 additional terms that apply to those files, or a notice indicating
 where to find the applicable terms.
 Additional terms, permissive or non-permissive, may be stated in the
 form of a separately written license, or stated as exceptions; the
 above requirements apply either way.
 #### 8. Termination.
 You may not propagate or modify a covered work except as expressly
 provided under this License. Any attempt otherwise to propagate or
 modify it is void, and will automatically terminate your rights under
 this License (including any patent licenses granted under the third
 paragraph of section 11).
 However, if you cease all violation of this License, then your license
 from a particular copyright holder is reinstated (a) provisionally,
 unless and until the copyright holder explicitly and finally
 terminates your license, and (b) permanently, if the copyright holder
 fails to notify you of the violation by some reasonable means prior to
 60 days after the cessation.
 Moreover, your license from a particular copyright holder is
 reinstated permanently if the copyright holder notifies you of the
 violation by some reasonable means, this is the first time you have
 received notice of violation of this License (for any work) from that
 copyright holder, and you cure the violation prior to 30 days after
 your receipt of the notice.
 Termination of your rights under this section does not terminate the
 licenses of parties who have received copies or rights from you under
 this License. If your rights have been terminated and not permanently
 reinstated, you do not qualify to receive new licenses for the same
 material under section 10.
 #### 9. Acceptance Not Required for Having Copies.
 You are not required to accept this License in order to receive or run
 a copy of the Program. Ancillary propagation of a covered work
 occurring solely as a consequence of using peer-to-peer transmission
 to receive a copy likewise does not require acceptance. However,
 nothing other than this License grants you permission to propagate or
 modify any covered work. These actions infringe copyright if you do
 not accept this License. Therefore, by modifying or propagating a
 covered work, you indicate your acceptance of this License to do so.
 #### 10. Automatic Licensing of Downstream Recipients.
 Each time you convey a covered work, the recipient automatically
 receives a license from the original licensors, to run, modify and
 propagate that work, subject to this License. You are not responsible
 for enforcing compliance by third parties with this License.
 An "entity transaction" is a transaction transferring control of an
 organization, or substantially all assets of one, or subdividing an
 organization, or merging organizations. If propagation of a covered
 work results from an entity transaction, each party to that
 transaction who receives a copy of the work also receives whatever
 licenses to the work the party's predecessor in interest had or could
 give under the previous paragraph, plus a right to possession of the
 Corresponding Source of the work from the predecessor in interest, if
 the predecessor has it or can get it with reasonable efforts.
 You may not impose any further restrictions on the exercise of the
 rights granted or affirmed under this License. For example, you may
 not impose a license fee, royalty, or other charge for exercise of
 rights granted under this License, and you may not initiate litigation
 (including a cross-claim or counterclaim in a lawsuit) alleging that
 any patent claim is infringed by making, using, selling, offering for
 sale, or importing the Program or any portion of it.
 #### 11. Patents.
 A "contributor" is a copyright holder who authorizes use under this
 License of the Program or a work on which the Program is based. The
 work thus licensed is called the contributor's "contributor version".
 A contributor's "essential patent claims" are all patent claims owned
 or controlled by the contributor, whether already acquired or
 hereafter acquired, that would be infringed by some manner, permitted
 by this License, of making, using, or selling its contributor version,
 but do not include claims that would be infringed only as a
 consequence of further modification of the contributor version. For
 purposes of this definition, "control" includes the right to grant
 patent sublicenses in a manner consistent with the requirements of
 this License.
 Each contributor grants you a non-exclusive, worldwide, royalty-free
 patent license under the contributor's essential patent claims, to
 make, use, sell, offer for sale, import and otherwise run, modify and
 propagate the contents of its contributor version.
 In the following three paragraphs, a "patent license" is any express
 agreement or commitment, however denominated, not to enforce a patent
 (such as an express permission to practice a patent or covenant not to
 sue for patent infringement). To "grant" such a patent license to a
 party means to make such an agreement or commitment not to enforce a
 patent against the party.
 If you convey a covered work, knowingly relying on a patent license,
 and the Corresponding Source of the work is not available for anyone
 to copy, free of charge and under the terms of this License, through a
 publicly available network server or other readily accessible means,
 then you must either (1) cause the Corresponding Source to be so
 available, or (2) arrange to deprive yourself of the benefit of the
 patent license for this particular work, or (3) arrange, in a manner
 consistent with the requirements of this License, to extend the patent
 license to downstream recipients. "Knowingly relying" means you have
 actual knowledge that, but for the patent license, your conveying the
 covered work in a country, or your recipient's use of the covered work
 in a country, would infringe one or more identifiable patents in that
 country that you have reason to believe are valid.
 If, pursuant to or in connection with a single transaction or
 arrangement, you convey, or propagate by procuring conveyance of, a
 covered work, and grant a patent license to some of the parties
 receiving the covered work authorizing them to use, propagate, modify
 or convey a specific copy of the covered work, then the patent license
 you grant is automatically extended to all recipients of the covered
 work and works based on it.
 A patent license is "discriminatory" if it does not include within the
 scope of its coverage, prohibits the exercise of, or is conditioned on
 the non-exercise of one or more of the rights that are specifically
 granted under this License. You may not convey a covered work if you
 are a party to an arrangement with a third party that is in the
 business of distributing software, under which you make payment to the
 third party based on the extent of your activity of conveying the
 work, and under which the third party grants, to any of the parties
 who would receive the covered work from you, a discriminatory patent
 license (a) in connection with copies of the covered work conveyed by
 you (or copies made from those copies), or (b) primarily for and in
 connection with specific products or compilations that contain the
 covered work, unless you entered into that arrangement, or that patent
 license was granted, prior to 28 March 2007.
 Nothing in this License shall be construed as excluding or limiting
 any implied license or other defenses to infringement that may
 otherwise be available to you under applicable patent law.
 #### 12. No Surrender of Others' Freedom.
 If conditions are imposed on you (whether by court order, agreement or
 otherwise) that contradict the conditions of this License, they do not
 excuse you from the conditions of this License. If you cannot convey a
 covered work so as to satisfy simultaneously your obligations under
 this License and any other pertinent obligations, then as a
 consequence you may not convey it at all. For example, if you agree to
 terms that obligate you to collect a royalty for further conveying
 from those to whom you convey the Program, the only way you could
 satisfy both those terms and this License would be to refrain entirely
 from conveying the Program.
 #### 13. Remote Network Interaction; Use with the GNU General Public License.
 Notwithstanding any other provision of this License, if you modify the
 Program, your modified version must prominently offer all users
 interacting with it remotely through a computer network (if your
 version supports such interaction) an opportunity to receive the
 Corresponding Source of your version by providing access to the
 Corresponding Source from a network server at no charge, through some
 standard or customary means of facilitating copying of software. This
 Corresponding Source shall include the Corresponding Source for any
 work covered by version 3 of the GNU General Public License that is
 incorporated pursuant to the following paragraph.
 Notwithstanding any other provision of this License, you have
 permission to link or combine any covered work with a work licensed
 under version 3 of the GNU General Public License into a single
 combined work, and to convey the resulting work. The terms of this
 License will continue to apply to the part which is the covered work,
 but the work with which it is combined will remain governed by version
 3 of the GNU General Public License.
 #### 14. Revised Versions of this License.
 The Free Software Foundation may publish revised and/or new versions
 of the GNU Affero General Public License from time to time. Such new
 versions will be similar in spirit to the present version, but may
 differ in detail to address new problems or concerns.
 Each version is given a distinguishing version number. If the Program
 specifies that a certain numbered version of the GNU Affero General
 Public License "or any later version" applies to it, you have the
 option of following the terms and conditions either of that numbered
 version or of any later version published by the Free Software
 Foundation. If the Program does not specify a version number of the
 GNU Affero General Public License, you may choose any version ever
 published by the Free Software Foundation.
 If the Program specifies that a proxy can decide which future versions
 of the GNU Affero General Public License can be used, that proxy's
 public statement of acceptance of a version permanently authorizes you
 to choose that version for the Program.
 Later license versions may give you additional or different
 permissions. However, no additional obligations are imposed on any
 author or copyright holder as a result of your choosing to follow a
 later version.
 #### 15. Disclaimer of Warranty.
 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT
 WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
 LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
 A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
 PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
 DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
 CORRECTION.
 #### 16. Limitation of Liability.
 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
 CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
 ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
 NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
 LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
 TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
 PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
 #### 17. Interpretation of Sections 15 and 16.
 If the disclaimer of warranty and limitation of liability provided
 above cannot be given local legal effect according to their terms,
 reviewing courts shall apply local law that most closely approximates
 an absolute waiver of all civil liability in connection with the
 Program, unless a warranty or assumption of liability accompanies a
 copy of the Program in return for a fee.
 END OF TERMS AND CONDITIONS
 ### How to Apply These Terms to Your New Programs
 If you develop a new program, and you want it to be of the greatest
 possible use to the public, the best way to achieve this is to make it
 free software which everyone can redistribute and change under these
 terms.
 To do so, attach the following notices to the program. It is safest to
 attach them to the start of each source file to most effectively state
 the exclusion of warranty; and each file should have at least the
 "copyright" line and a pointer to where the full notice is found.
        <one line to give the program's name and a brief idea of what it does.>
        Copyright (C) <year>  <name of author>
        This program is free software: you can redistribute it and/or modify
        it under the terms of the GNU Affero General Public License as
        published by the Free Software Foundation, either version 3 of the
        License, or (at your option) any later version.
        This program is distributed in the hope that it will be useful,
        but WITHOUT ANY WARRANTY; without even the implied warranty of
        MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
        GNU Affero General Public License for more details.
        You should have received a copy of the GNU Affero General Public License
        along with this program.  If not, see <https://www.gnu.org/licenses/>.
 Also add information on how to contact you by electronic and paper
 mail.
 If your software can interact with users remotely through a computer
 network, you should also make sure that it provides a way for users to
 get its source. For example, if your program is a web application, its
 interface could display a "Source" link that leads users to an archive
 of the code. There are many ways you could offer source, and different
 solutions will be better for different programs; see section 13 for
 the specific requirements.
 You should also get your employer (if you work as a programmer) or
 school, if any, to sign a "copyright disclaimer" for the program, if
 necessary. For more information on this, and how to apply and follow
 the GNU AGPL, see <https://www.gnu.org/licenses/>.

 1. **SSH Public key**: self-explanatory. Add your public key to your user attrset under `sshPubKeys`.
 2. **Wireguard device**: each wireguard device has two parts: the public key and the IP addresses it should have in the wireguard network. The pub.solar wireguard network is spaced under `10.7.6.0/24` and `fd00:fae:fae:fae:fae::/80`. To add your device, it's best to choose a free number between 200 and 255 and use that in both the ipv4 and ipv6 ranges: `10.7.6.<ip-address>/32` `fd00:fae:fae:fae:fae:<ip-address>::/96`.

 # Delete accounts without verified email address
 ### Keycloak
 Required:
 - auth.pub.solar admin-cli service user credentials
 - [SSH access to host `nachtigall`](../administrative-access.md#ssh-access)
 Run following after SSH'ing to `nachtigall`.
 Credentials for the following command are in keepass. Create a keycloak
 config/credentials file at `/tmp/kcadm.config`:
 ```
 sudo --user keycloak kcadm.sh config credentials \
  --config /tmp/kcadm.config \
  --server https://auth.pub.solar \
  --realm pub.solar \
  --client admin-cli
 ```
 Get list of accounts without a verified email address:
 ```
 sudo --user keycloak kcadm.sh get \
  --config /tmp/kcadm.config \
  users \
  --realm pub.solar \
  --query emailVerified=false \
  > /tmp/keycloak-unverified-accounts
 ```
 Review list of accounts, especially check `createdTimestamp` if any accounts
 were created in the past 2 days. If so, delete those from the
 `/tmp/keycloak-unverified-accounts` file.
 ```
 createdTimestamps=( $( nix run nixpkgs#jq -- -r '.[].createdTimestamp' < /tmp/keycloak-unverified-accounts ) )
 # timestamps are in nanoseconds since epoch, so we need to strip the last three digits
 for timestamp in ${createdTimestamps[@]}; do date --date="@${timestamp::-3}"; done
 vim /tmp/keycloak-unverified-accounts
 ```
 Check how many accounts are going to be deleted:
 ```
 jq -r '.[].id' < /tmp/keycloak-unverified-accounts | wc -l
 ```
 ```
 jq -r '.[].id' < /tmp/keycloak-unverified-accounts > /tmp/keycloak-unverified-account-ids
 ```
 Final check before deletion (dry-run):
 ```
 for id in $(cat /tmp/keycloak-unverified-account-ids)
  do
    echo sudo --user keycloak kcadm.sh delete \
      --config /tmp/kcadm.config \
      users/$id \
      --realm pub.solar
  done
 ```
 THIS WILL DELETE ACCOUNTS:
 ```
 for id in $(cat /tmp/keycloak-unverified-account-ids)
  do
    sudo --user keycloak kcadm.sh delete \
      --config /tmp/kcadm.config \

 # Unlocking the root partition on boot
 After a boot, the encrypted root partition will have to be unlocked. This is done by accessing the server via SSH with user root on port 2222.
 ```
 ssh root@nachtigall.pub.solar -p2222
 ```
 After connecting, paste the crypt passphrase you can find in the shared keepass. This will disconnect the SSH session right away and the server will keep booting into stage 2.

 # Unlocking the ZFS pool on boot
 After a reboot, the encrypted ZFS pool will have to be unlocked. This is done by
 accessing the server via SSH as user `root` on port 2222.
 Nachtigall:
 ```
 ssh -4 root@nachtigall.pub.solar -p2222
 ```
 Metronom:
 ```
 ssh -4 root@metronom.pub.solar -p2222
 ```
 After connecting, paste the encryption passphrase you can find in the shared
 keepass. This will disconnect the SSH session immediately and the server will
 continue to boot into stage 2.
