Clarify that the monochrome font is not included, per #221181.
The new name is also coherent with the name of the font,
according to `fontconfig`: Noto Color Emoji.

Implements the new option `security.acme.maxConcurrentRenewals` to limit
the number of certificate generation (or renewal) jobs that can run in
parallel. This avoids overloading the system resources with many
certificates or running into acme registry rate limits and network
timeouts.
Architecture considerations:
- simplicity, lightweight: Concerns have been voiced about making this
already rather complex module even more convoluted. Additionally,
locking solutions shall not significantly increase performance and
footprint of individual job runs.
To accomodate these concerns, this solution is implemented purely in
Nix, bash, and using the light-weight `flock` util. To reduce
complexity, jobs are already assigned their lockfile slot at system
build time instead of dynamic locking and retrying. This comes at the
cost of not always maxing out the permitted concurrency at runtime.
- no stale locks: Limiting concurrency via locking mechanism is usually
approached with semaphores. Unfortunately, both SysV as well as
POSIX-Semaphores are *not* released when the process currently locking
them is SIGKILLed. This poses the danger of stale locks staying around
and certificate renewal being blocked from running altogether.
`flock` locks though are released when the process holding the file
descriptor of the lock file is KILLed or terminated.
- lockfile generation: Lock files could either be created at build time
in the Nix store or at script runtime in a idempotent manner.
While the latter would be simpler to achieve, we might exceed the number
of permitted concurrent runs during a system switch: Already running
jobs are still locked on the existing lock files, while jobs started
after the system switch will acquire locks on freshly created files,
not being blocked by the still running services.
For this reason, locks are generated and managed at runtime in the
shared state directory `/var/lib/locks/`.

Add NixOS test for QGIS and QGIS-LTR. This test creates QGIS vector
memory layer containing Nix snowflake. This proves that application can
successfully start and Python bindings are working.
By default, Python script is executed in non-interactive mode and QGIS
is closed after script is finished. This script can be also executed
interactively by running following command:
```
nix-build -A qgis
QGIS_TEST_INTERACTIVE=True ./result/bin/qgis --code pkgs/applications/gis/qgis/test.py
```
In this case, QGIS is not automatically closed.
Just like with system-wide tmpfiles, call `systemd-tmpfiles --create
--remove` for users during activation. This fixes an issue where new
entries in a user's tmpfiles are not reflected after activation, only at
boot when the user service systemd-tmpfiles-setup.service runs or only
after running systemd-tmpfiles manually.
Before this change it was crucial that nonprivileged users are unable to
create hardlinks to SUID wrappers, lest they be able to provide a
different `.real` file alongside. That was ensured by not providing a
location writable to them in the /run/wrappers tmpfs, (unless
disabled) by the fs.protected_hardlinks=1 sysctl, and by the explicit
own-path check in the wrapper. After this change, ensuring
that property is no longer important, and the check is most likely
redundant.
The simplification of expectations of the wrapper will make it
easier to remove some of the assertions in the wrapper (which currently
cause the wrapper to fail in no_new_privs environments, instead of
executing the target with non-elevated privileges).
Note that wrappers had to be copied (not symlinked) into /run/wrappers
due to the SUID/capability bits, and they couldn't be hard/softlinks of
each other due to those bits potentially differing. Thus, this change
doesn't increase the amount of memory used by /run/wrappers.
This change removes part of the test that is obsoleted by the removal of
`.real` files.
Wrappers generate pieces of apparmor policies for inclusion, which are
used only in a single place in nixpkgs, for `ping`. They are built only
if apparmor is enabled.
This change causes the test to test:
- that the apparmor includes can be generated,
- that `ping` works with apparmor enabled (as the only policy that
references these includes).
Ideally there would be some other NixOS test that verifies that `ping`
specifically works. Sadly, there isn't one.
This contribution adds `odoo15` as a fixed version. To allow reusing the
existing test for Odoo, I made the package attribute configurable. To
reference the test for `odoo15` in `passthru` I added it to
`all-tests.nix`.
There's no "lib" in scope here. The test uses "with pkgs.lib;", so
this failed to evaluate.

Previously, the transactional template was in id=2.
It is now id=3.
I moved a bit the code to improve the ability to load templates and subscribers properly.
I am planning to upstream `type` for templates API request so we can easily filter out
and select the accordingly template.
We should sometimes restart the units rather than reloading them so the
changes are actually applied. / and /nix are explicitly excluded because
there was some very old issue where these were unmounted. I don't think
this will affect many people since most people use fstab mounts instead
but I plan to adapt this behavior for fstab mounts as well in the future
(once I wrote a test for the fstab thingies).
I have removed myself as maintainer from those packages that:
* Have at least one other maintainer
* Are outside of my actual expertise,
i.e. I wouldn't really know how to fix them if they broke
