This will also list the generations of other profiles than system in
the boot menu. See the documentation of the --profile-name option of
nixos-rebuild for more information on profiles.

Motivation for this change

To boot other profiles with systemd-boot.

Things done
  • Tested using sandboxing
    (nix.useSandbox on NixOS,
    or option build-use-sandbox in nix.conf
    on non-NixOS)
  • Built on platform(s)
    • NixOS
    • macOS
    • Linux
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Fits CONTRIBUTING.md.

Sorry, something went wrong.

Suppose you want to have different kernel version. You can create a profile for each and get a boot menu entry to select them.

Would not this fail to match old entries?

Here as well. We need backward-compatible code.

This is with intent. The rex_profile regex is used to decide if it is a system profile or not.

Currently fails to build, when I give no profile argument to nixos-rebuild switch:

Ohh, I should have checked the case that no profile exists. My bad, I will update the PR but will only have time earliest on Monday to do so.
