This patch adds handling of a directory becoming a symlink in /etc. Before this patch, the directory wasn't removed and then symlinking failed, which caused directory not being updated at all. The idea for the patch goes to @abbradar at https://github.com/NixOS/nixpkgs/issues/16978#issuecomment-232921903: > A heuristic idea for this -- a function `isStatic :: Path -> Bool`: > > * if path `/etc/foo` is a file, return True iff it's a symlink to `/etc/static/foo`. > * if path is a directory, return True iff for all items in it `isStatic` is True. > > On any conflicts, if old path is static, it's safe to replace and/or > delete stale. Otherwise make a backup and notify the user via a > journal entry and console output. The only difference here -- it will not replace user configs. This also fixes https://github.com/NixOS/nixpkgs/issues/16978. |
