Previously we had our libraries in a subdirectory of /var/lib/copyparty
While that's an OK idea in theory, in practice it'd require us to make every directory on the way to /var/lib/copyparty/data/groups/library +rx to kavita. That's something we're unwilling to do. The true fix is to move this out so we don't have to meddle with permissions except those which are directly on this directory
