Ok, I took Jóhann's idea and ran with it, trying to preserve as much
of the functionality of the sysv init script as I could. It turn out
the need to change device permissions is only for people who want to
run mythbackend as a real user, not root. I'm not sure if the
following is valid, but here it is:
[Unit]
Description=MythTV backend service
After=network.target mysqld.service
[Service]
Type=forking
PIDFile=/var/run/mythbackend.pid
EnvironmentFile=-/etc/sysconfig/mythbackend
Environment=MYTHCONFDIR=${MYTHTV_HOME:-/etc/mythtv}
Environment=HOME=${MYTHTV_HOME:-/etc/mythtv}
Environment=MYTHBACKEND_USER=${MYTHBACKEND_USER:-root}
ExecStart=/usr/bin/mythbackend --daemon --user $MYTHBACKEND_USER
--logfile /var/log/mythtv/mythbackend.log --pidfile
/var/run/mythbackend.pid
[Install]
WantedBy=multi-user.target
Thanks,
