# Our next problem is the "Resources" directory in /usr/lib/plexmediaserver.
# This is ostensibly a skeleton directory, which contains files that Plex
# copies into its folder in /var. Unfortunately, there are some SQLite
# databases in the directory that are opened at startup. Since these
# database files are read-only, SQLite chokes and Plex fails to start. To
# solve this, we keep the resources directory in the Nix store, but we
# rename the database files and replace the originals with symlinks to
# /var/lib/plex. Then, in the systemd unit, the base database files are
# copied to /var/lib/plex before starting Plex.
