I came across this reddit thread discussing the
system.nixos.label option and the
NIXOS_LABEL environment variable.
They seem to have no effect with
systemd-boot, so I was wondering if anyone knows how I can customize how the generations appear in the bootloader. I’d like to include the git commit hash & message.
The script building the entries should be this and the entry is build specifically here. But it seems it does not have any support for having the NIXOS_LABEL thing.
Possibly that is somehow refering to that as i found code writing the system.nixos.label to nixos-version, but actually idk how they are connected
edit x: actually it seems that config.system.nixos.label does match with what is written do the description, at least for my system.
version Generation 699 NixOS iamatest, Linux Kernel 6.1.53-xanmod1, Built on 2023-09-21
system.nixos.label = "iamatest";
