what do you have in ./doom? this looks like the doom cli is trying to write a file in the nix store

In reply to @roman.gonzalez:matrix.org
at this point, I would recommend reverting the evil-collection dependency resolution to come from emacs (e.g. remove it from the overrides.nix). This may work for Linux folks so no need to stop that from happening.
i've just switched over to nix-doom-emacs and run straight into this issue, so i'm in favour of this fix at least in the short term
