I might be answering my own question

but I saw this on the MythTV wiki

http://www.mythtv.org/wiki/Systemd_mythbackend_Configuration

should this be in the latest FC package for MythtTV
ie
/etc/systemd/system/mythbackend.service

Paul

Check the archives for "Re: [ATrpms-devel] mythbackend fails to start on boot; mysqld not ready"
What I wrote in my last message on 5/19/2012 is still working well. I did make a /etc/tmpfiles.d/mythbackend.conf containing:

d /var/run/mythtv 0755 mythtv mythtv -

Hope that helps!

Note I did find a systemctl config file which did the trick anyway but

So what does this tmpfiles.d do?

From memory, it creates the run directory where the process's pid will be kept so systemd knows the proper status...so systemctl 'stats', 'reload' or 'restart' commands work as they should.

Charles:

I'm not sure why Axel isn't currently building kmdls for nvidia on
FC17. I've built my own for x86_64, but haven't had a chance to test
them. There is a recent thread discussing how to build them.

I ran into this before and found where someone said just include a delay
in the mythbackend startup script (edit /etc/rc.d/init.d/mythbackend and
change/add: sleep ## <-- number of seconds 5 - 10 works), that has been
working for me.

# daemon --user mythtv $binary $OPTIONS
daemonsleep 10; $binary $OPTIONS
Hope this helps.

should be a space between daemon and sleep. Sorry for the new thread
and top post on the previous message one too many mail programs open.

I just noticed this in the syslog too

mythbox systemd-tmpfiles[29725]: stat(/run/user/mythtv/gvfs) failed: Permission denied

any idea?

Rather than try to find the best sleep value, I added this bit of code
before mythbackend actually starts:
#Wait for mysql to start, up to 60 seconds

for i in {1..60}
do
if mysql -u mythtv -pPassword </dev/null >/dev/null 2>&1 ; then
break
fi
sleep 1s;
done


So it checks once a second to see if it can connect, 60 times. It will wait
up to a minute, then continue anyway -- and mythbackend will fail, but if it
isn't up after a minute something is wrong.

This works fine for me using FC16 x86_64 and Axel's builds. I don't
seem to have any permission problems. I don't think I had to set any
special permissions on any files.

Note the systemd now looks after the pre-req of MySQLd, the latest issue
was some DVB devices taking sometime to initialized but the sleep / delay
seems to have worked for me.

George,
do you allow read/write to your "/var/lib/mythtv/config.xml"

Yes, the mythtv user owns the mythtv subdirectory under /var/lib and
can write to that directory and also owns the config.xml file.
Obviously /var/lib itself is not writable by mythtv.
