On my MacBook Air running NixOS 20.03, nix-collect-garbage -d
works except it doesn’t delete the previous .conf
in /boot/loader/entries
so I have to delete it manually. I’m wondering how I can get it to work fully and if there is something critically wrong with my system.

there’s most likely a program still running from that generation , so nixos still sees it as “in-use”. If you do a nixos-rebuild switch
it will usually tell you what services it skipped restarting due to potential conflicts.

Sorry, I forgot respond to this thread. Appreciate your response @jonringer (and your work on nixos).
Even after I restart and run nix-collect-garbage -d
, the generation isn’t deleted. Whenever I run nixos-rebuild
, /boot/loader/entries
is repopulated with the previous twenty-something generations even though I have deleted them.
For boot entries you need to:
- Run GC as root to make them stale
- Rebuild and switch your system, such that the activation script removes the stale entries.
Nix GC will always only affect /nix/*
, never /boot
!
