openSUSE isn't properly supported

https://www.plex.tv/downloads doesn't have an openSUSE edition, so I downloaded the Fedora RPM and it doesn't work.

According to the work of @sammy2k8, @damonbane and the good people at opensuse-forum (specifically luke2235), this is what you need to do after installing the rpm:

create plex group in yast and add plex user to the group
change ownership of /var/lib/plexmediaserver (sudo chown : plex /var/lib/plexmediaserver)
give plex group write permission to this directory (sudo chmod g+w /var/lib/plexmediaserver)
sudo systemctl restart plexmediaserver && sudo systemctl enable plexmediaserver to restart and enable plex
