Would it be possible to put the specialisation back in the front of each boot entry?

Please also see my related question on discourse.

For reference, without Lanzaboot this is typically what the same entries would look like with two specialisations testA and testB

Once secure boot is enabled using Lanzaboote the name of the specialisation seems to be removed from each boot entry or is perhaps truncated from view on the right side of the screen. This is what I see. ``` NixOS Uakari My-Comment-Two (Linux 6.6.51) (Generation 10, Built on 2024-10-13) (nixos-generation-10 NixOS Uakari My-Comment-Two (Linux 6.6.51) (Generation 10, Built on 2024-10-13) (nixos-generation-10 NixOS Uakari My-Comment-Two (Linux 6.6.51) (Generation 10, Built on 2024-10-13) (nixos-generation-10 ``` Would it be possible to put the specialisation back in the front of each boot entry?

I tried a shorter system.nixos.label with lib.mkForce this morning.

Main config -> system.nixos.label = "main";
Specialisation -> system.nixos.label = lib.mkForce "testA";

The label from the specialisation was applied to both boot entries.

What was interesting here, is that with a very short label I can see the start of the word specialisation at the end of the boot string, being cropped by an apparent 100 char display limit for systemd, even though I have extra room on the screen. I have tried the various console options, but nothing seems to show more than 100 characters.
