I personally know at least 3 other people in the lojban community who use nix

actually four now that I think about Xe

That's a good thought, I should try that after I see if enabling home-manager's fonts.fontconfig option

Actually looks like enabling fontconfig did it

Hi, sorry for the kind of noob question, but I'm trying to install nix-doom-emacs with home-manager and flakes but I got this error:

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.
