# [`bud`][bud] command
The template incudes a convenient script for managing your system called [`bud`][bud].
It is a portable and highly composable system control tool that work anywhere on your host
or in the flake's devshell.
Although it comes with some predefined standard helpers,
it is very extensible and you are encouraged to write your own script snippets
to ease your workflows. An example is the bud module for a `get` command that
comes included with `devos`.
While writing scripts you can convenientely access smart environment variables
that can tell the current architecture, user or host name, among others, regardless
wether you invoke `bud` within the devshell or as the system-wide installed `bud`.
For details, please review the [bud repo][bud].

# Bootstrapping
This will help you boostrap a bare host with the help of the
[bespoke iso](./iso.md) live installer.
_Note: nothing prevents you from remotely executing the boostrapping
process. See below._
Once your target host has booted into the live iso, you need to partition
and format your disk according to the [official manual][manual].
## Mount partitions
Then properly mount the formatted partitions at `/mnt`, so that you can
install your system to those new partitions.
Mount `nixos` partition to `/mnt` and &mdash; for UEFI &mdash; `boot`
partition to `/mnt/boot`:
```console
$ mount /dev/disk/by-label/nixos /mnt
$ mkdir -p /mnt/boot && mount /dev/disk/by-label/boot /mnt/boot # UEFI only
$ swapon /dev/disk/by-label/swap
```
Add some extra space to the store. In the iso, it's running on a tmpfs
off your RAM:
```console
$ mkdir -p /mnt/tmpstore/{work,store}
$ mount -t overlay overlay -olowerdir=/nix/store,upperdir=/mnt/tmpstore/store,workdir=/mnt/tmpstore/work /nix/store
```
## Install
Install off of a copy of devos from the time the iso was built:
```console
$ cd /iso/devos
$ nixos-install --flake .#NixOS
```
## Notes of interest
### Remote access to the live installer
The iso live installer comes preconfigured with a network configuration
which announces it's hostname via [MulticastDNS][mDNS] as `hostname.local`,
that is `bootstrap.local` in the [iso example](./iso).
In the rare case that [MulticastDNS][mDNS] is not availabe or turned off
in your network, there is a static link-local IPv6 address configured to
`fe80::47`(mnemonic from the letter's position in the english alphabet:
`n=14 i=9 x=24; 47 = n+i+x`).
Provided that you have added your public key to the authorized keys of the
`root` user _(hint: [`deploy-rs`](../integrations/deploy.md) needs passwordless
sudo access)_:
```nix
{ ... }:
{
users.users.root.openssh.authorizedKeys.keyFiles = [
../secrets/path/to/key.pub
];
}
```
You can then ssh into the live installer through one of the
following options:
```console
ssh root@bootstrap.local
ssh root@fe80::47%eno1 # where eno1 is your network interface on which you are linked to the target
```
_Note: the [static link-local IPv6 address][staticLLA] and [MulticastDNS][mDNS] is only
configured on the live installer. If you wish to enable [MulticastDNS][mDNS]
for your environment, you ought to configure that in a regular [profile](../concepts/profiles.md)._
### EUI-64 LLA & Host Identity
The iso's IPv6 Link Local Address (LLA) is configured with a static 64-bit Extended
Unique Identifiers (EUI-64) that is derived from the host interface's Message
Authentication Code (MAC) address.
After a little while (a few seconds), you can remotely discover this unique and host
specific address over [NDP][NDP] for example with:
```console
ip -6 neigh show # also shows fe80::47
```
***This LLA is stable for the host, unless you need to swap that particular network card.***
Under this reservation, though, you may use this EUI-64 to wire up a specific
(cryptographic) host identity.

# From NixOS
## Generate Configuration
Assuming you're happy with your existing partition layout, you can generate a
basic NixOS configuration for your system using:
```sh
bud up
```
This will make a new file `hosts/up-$(hostname).nix`, which you can edit to
your liking.
You must then add a host to `nixos.hosts` in flake.nix:
```nix
{
nixos.hosts = {
modules = hosts/NixOS.nix;
};
}
```
Make sure your `i18n.defaultLocale` and `time.timeZone` are set properly for
your region. Keep in mind that `networking.hostName` will be automatically
set to the name of your host;
Now might be a good time to read the docs on [suites](../concepts/suites.md) and
[profiles](../concepts/profiles.md) and add or create any that you need.
> ##### _Note:_
> While the `up` sub-command is provided as a convenience to quickly set up and
> install a "fresh" NixOS system on current hardware, committing these files is
> discouraged.
>
> They are placed in the git staging area automatically because they would be
> invisible to the flake otherwise, but it is best to move what you need from
> them directly into a host module of your own making, and commit that instead.
# Installation
Once you're ready to deploy `hosts/my-host.nix`:
```sh
bud my-host switch
```
This calls `nixos-rebuild` with sudo to build and install your configuration.
> ##### _Notes:_
> - Instead of `switch`, you can pass `build`, `test`, `boot`, etc just as with
> `nixos-rebuild`.

The only dependency is nix, so make sure you have it [installed][install-nix].
## Get the Template
Here is a snippet that will get you the template without the git history:
If you currently don't have flakes setup, you can utilize the digga shell to pull the template:
```sh
nix-shell -p cachix --run "cachix use nrdxp"
nix-shell https://github.com/divnix/devos/archive/main.tar.gz -A shell \
--run "bud get main"
cd devos
nix-shell
nix-shell "https://github.com/divnix/digga/archive/main.tar.gz" \
--run "nix flake init -t github:divnix/digga"
```
If you already have flakes support, you can directly pull the template:
```sh
nix flake init -t github:divnix/digga
```
Then make sure to create the git repository:
```sh
git init
git add .
git commit -m init
```
This will place you in a new folder named `devos` with git initialized, and a
nix-shell that provides all the dependencies, including the unstable nix
version required.
To drop into a nix-shell, if you don't have flakes setup, use the digga shell to create a `flake.lock`:
```sh
nix-shell "https://github.com/divnix/digga/archive/main.tar.gz" \
--run "nix flake lock"
```
Or if you do have flakes support, just run:
```sh
nix flake lock
```
Finally, run `nix-shell` to get to an interactive shell with all the dependencies, including the unstable nix
version required. You can run `menu` to confirm that you are using digga (expected output includes [docs], [general commands], [linter], etc.).
In addition, the [binary cache](../integrations/cachix.md) is added for faster deployment.

# ISO
# Installation Media
This project leverages [nix-community/nixos-generators][nixos-generators] for
building machine images. In most cases, you'll probably want to use the
`install-iso` format.
Making an installable ISO for `hosts/bootstrap.nix` is as simple as:
Making and writing an installable iso for `hosts/bootstrap.nix` is as simple as:
```sh
bud build bootstrap bootstrapIso
sudo -E $(which bud) burn
nix run github:nix-community/nixos-generators -- \
--format install-iso \
--flake '.#bootstrap'
```
This works for any host.
Then "burn" the ISO to your USB stick (or CD-R if you like!) following the
[instructions in the NixOS manual][burn] (or using your preferred USB burner).
## ISO image nix store & cache
You can also swap out the `--format` for [any of the others][formats] supported
by nixos-generators.
The iso image holds the store to the live environment and _also_ acts as a binary cache
to the installer. To considerably speed up things, the image already includes all flake
`inputs` as well as the `devshell` closures.
Continue by following the usual installation instructions in the NixOS manual.
While you _could_ provision any machine with a single stick, a custom-made iso for
the host you want to install DevOS to, maximises those local cache hits.
## ISO Nix Store and Cache
For hosts that don't differ too much, a single usb stick might be ok, whereas when
there are bigger differences, a custom-made usb stick will be considerably faster.
