RPM reinstall leaves behind old /nix/store paths

[jalil-salame]

When building a bundle (e.g. nix bundle --bundler github:NixOS/bundlers#toRPM nixpkgs-stable#hello), installing it and then reinstalling it with a new version (e.g. nix bundle --bundler github:NixOS/bundlers#toRPM nixpkgs-unstable#hello), the reinstall leaves behind old files (e.g. /nix/store/$HASH-zstd-$VERSION).

Note

I am reinstalling with sudo rpm -ivh --reinstall /path/to/prog.rpm.

Current workarounds

Before reinstalling an RPM built with nix bundle remove all files associated with it (sudo dnf remove $RPM_NAME), then install it.

Proposed solution

I have no idea how RPMs work, but I'd expect there to be a way to specify that when it reinstalls it should delete old files(?).
