instead of installing everything as rpm, it could install it as brew and just mount brew automatically at distrobox creation, so when using fzf and entering the distrobox you don’t get welcome with “fzf: command not found”
Not everyone wants brew in their distroboxes.
However, to avoid duplication, you can add the path to the host’s linuxbrew to the distrobox, then add it to the path in the distrobox.
