I was looking at the garbage collector roots on my system and I noticed some that surprised me:
/nix/var/nix/gcroots/auto/1d5... -> /root/.tmp /nix/var/nix/gcroots/auto/7h9... -> /root/result
Looking at what they link to:
/root/.tmp -> /nix/store/...-nixos-system-nixos-22.05.20221230.0c5a734 /root/result -> /nix/store/...-nixos-system-nixos-20.03.20200622.13c15f2
Does anyone know what might’ve created these, and whether it’s safe to remove them? They seem to be referencing older nixos releases than I’m currently running.
