LGTM!

Seems harmless.

This broke my setup as I now get this

error: builder for '/nix/store/vbfgzglpq417kvkhs12ibz7778s4mjrl-home-manager-files.drv' failed with exit code 1;
       last 1 log lines:
       > Error installing file '.icons/default/index.theme' outside $HOME

Unclear to me why though.

Is it possible your folder .icons is a symlink to a folder outside home?

As far as I can tell .icons is being generated by home-manager

❯ ls $HOME/.icons
Permissions Size User     Date Modified Name
lrwxrwxrwx    77 bemeurer  9 Jun 22:46  default -> /nix/store/mg4hkybs1qijhapy12nqm6sgn70jf40z-home-manager-files/.icons/default/

Interesting… I didn't see anywhere in the current home-manager source that home.file.".icons/…" was being set. So it would help to figure out where this comes from.

It looks like .icons/default/ is indeed a directory, but the conflicting module is linking the whole directory rather than individual files which would make it (more likely) possible to merge them. What's in the directory – is it also index.theme or other files?

I'll open a PR reverting this in the meantime.

This is still failing for me, I'll make a reversal PR :)
