Thanks for this. I didn't realize. But if the backend depends on
mysql, why not (for the moment) build in a delay untill mysql is
started?
(this snipped I added to /usr/share/mythtv/mythfrontend.sh)
delay=30
    while [ ! -e "/var/run/mysqld/mysqld.pid" ] && [ "$delay" -gt "0" ]; do
       let delay--
       sleep 1
       echo "No database yet , sleeping for $delay seconds" | tee -a
$MYTHWELCOMELOG
    done

I wish:-) No it is an ordinary dual core E7400 with an even more ordinary HD..
But from the logs  I see that they start about the same time.

Would it be possible to build a check for the mythbackend proces and
lirc daemon in mythfrontend.sh, like I did above with mysql?
Would that solve the race?
