* Misc NixOS Configurations
|
||
|
||
This module hosts some misc configuration I am unsure where to put
|
||
elsewhere than here. Don’t expect this file to be coherent, but expect
|
||
it to be quite short.
|
||
|
||
This module declares the aspect =nixos.misc=, which is used by all my
|
||
hosts.
|
||
|
||
#+begin_src nix :tangle yes
|
||
{
|
||
flake.modules.nixos.misc = {
|
||
lib,
|
||
config,
|
||
...
|
||
}:
|
||
with lib; let
|
||
cfg = config.mySystem.misc;
|
||
in {
|
||
<<timezone-option>>
|
||
<<layout-option>>
|
||
|
||
config = {
|
||
<<layout-config>>
|
||
<<timezone-config>>
|
||
<<envfs>>
|
||
<<orca>>
|
||
<<clean-tmp>>
|
||
<<completion>>
|
||
};
|
||
};
|
||
}
|
||
#+end_src
|
||
|
||
** System Timezone
|
||
First, let me declare the timezone. I’ll set it as an option, as not
|
||
all my machines live in the same place, but I’ll default to
|
||
Metropolitan France’s timezone.
|
||
#+name: timezone-option
|
||
#+begin_src nix
|
||
options.mySystem.misc.timezone = mkOption {
|
||
type = types.str;
|
||
default = "Europe/Paris";
|
||
};
|
||
#+end_src
|
||
|
||
Now, I can set it for my system.
|
||
#+name: timezone-config
|
||
#+begin_src nix
|
||
time.timeZone = cfg.timezone;
|
||
#+end_src
|
||
|
||
** TTY Keyboard Layout
|
||
Now, I can set the TTY’s keyboard config. Most of my machines use the
|
||
Bépo layout everywhere, but I do share one whose owner doesn’t use it,
|
||
so I’ll let this as an option to be set, defaulting to the default
|
||
French layout.
|
||
#+name: layout-option
|
||
#+begin_src nix
|
||
options.mySystem.misc.keymap = mkOption {
|
||
type = types.str;
|
||
default = "fr";
|
||
example = "fr-bepo";
|
||
description = "Keymap to use in the TTY console";
|
||
};
|
||
#+end_src
|
||
|
||
Now, I can set it on my system.
|
||
#+name: layout-config
|
||
#+begin_src nix
|
||
console.keyMap = cfg.keymap;
|
||
#+end_src
|
||
|
||
** Truly Miscelaneous Config
|
||
First, some scripts are written with the assumption that some
|
||
utilities are always in the same place, such as =/bin/bash=. It is,
|
||
however, not always the case with NixOS. Mic92’s [[https://github.com/Mic92/envfs][envfs]] solves that.
|
||
#+name: envfs
|
||
#+begin_src nix
|
||
services.envfs.enable = true;
|
||
#+end_src
|
||
|
||
I have no idea why, but sometimes, [[https://orca.gnome.org/][Orca]] get activated without my
|
||
consent. So I hard-disable it here.
|
||
#+name: orca
|
||
#+begin_src nix
|
||
services.orca.enable = false;
|
||
#+end_src
|
||
|
||
I was surprised to see =/tmp= still hold the same files after my first
|
||
reboot in NixOS, I always assumed it was cleared on every reboot on
|
||
every system. But I can enable this behaviour back.
|
||
#+name: clean-tmp
|
||
#+begin_src nix
|
||
boot.tmp.cleanOnBoot = true;
|
||
#+end_src
|
||
|
||
Lastly, I want to make sure my shell completions work, so I’ll enable
|
||
this.
|
||
#+name: completion
|
||
#+begin_src nix
|
||
environment.pathsToLink = [
|
||
"/share/bash-completion"
|
||
"/share/zsh"
|
||
];
|
||
#+end_src
