I use Nix with home-manager (unstable channel) on several Debian machines for about two dozen packages which do not exist/are too old in Debian.
home-manager switch failed due to a bug in one library. That’s fine, I understand what ‘unstable channel’ means.
But I realised that I do not know how to update selectively some of the packages not affected by the bug. If I comment packages out in
home.nix, they get deinstalled.
Is an update of single packages possible with home-manager?
