Checking the keyboard layout has been a long set of hurdles so far, with several attempts. Originally, the checking was introduced by @lheckemann in #23709. The initial implementation just was trying to check whether the symbols/ directory contained the layout name. Unfortunately, that wasn't enough and keyboard variants weren't recognized, so if you set layout to eg. "dvorak" it will fail with an error (#25526). So my improvement on that was to use sed to filter rules/base.lst and match the layout against that. I fucked up twice with this, first because layout can be a comma-separated list which I didn't account for and second because I ran into a Nix issue (NixOS/nix#1426). After fixing this, it still wasn't enough (and this is btw. what localectl also does), because we were *only* matching rules but not symbols, so using "eu" as a layout won't work either. I decided now it's the time to actually use libxkbcommon to try compiling the keyboard options and see whether it succeeds. This comes in the form of a helper tool called xkbvalidate. IMHO this approach is a lot less error-prone and we can be sure that we don't forget about anything because that's what the X server itself uses to compile the keymap. Another advantage of this is that we now validate the full set of XKB options rather than just the layout. Tested this against a variety of wrong and correct keyboard configurations and against the "keymap" NixOS VM tests.

Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels git://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-17.03 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-17.03
For pull-requests, please rebase onto nixpkgs master.
NixOS linux distribution source code is located inside
nixos/ folder.
