DISABLE_AUTOFORMATTING="yes"
DOC_CONTENTS="
To have this machine operate as recording host for MythTV,
mythbackend must be running. Run the following:
rc-update add mythbackend default

Your recordings folder must be owned 'mythtv'. e.g.
chown -R mythtv /var/lib/mythtv

Want mythfrontend to start automatically?
Set USE=autostart. Details can be found at:
https://dev.gentoo.org/~cardoe/mythtv/autostart.html

Note that the systemd unit now restarts by default and logs
to journald via the console at the notice verbosity.
