after some googling, i have found something i could do and it worked!
you have to put the start-skripts for the different runlevels AFTER avahi!
so, for me it was:
in the directories
/etc/rc.d/rc3.d/
/etc/rc.d/rc4.d/ (why the hell ever runlevel 4)
/etc/rc.d/rc5.d/
mv S85mt-daapd S99mt-daapd
after a reboot it worked like a charm!
this would lead to my next question…
how can i post a bugfix suggestion to the fedora team? 😉
