Thanks for that - so it seems the problem is caused by the default
start order of the services, where NetworkManager starts after

[root localhost ~]# ls -l /etc/rc.d/rc5.d | grep S | egrep 'sshd|NetworkManager|avahi-daemon'
lrwxrwxrwx 1 root root 14 2007-12-29 23:39 S55sshd -> ../init.d/sshd
lrwxrwxrwx 1 root root 22 2007-12-29 23:28 S96avahi-daemon -> ../init.d/avahi-daemon
lrwxrwxrwx 1 root root 24 2007-12-29 13:48 S98NetworkManager -> ../init.d/NetworkManager

I will try to change the start priority of avahi-daemon from 96 to 99
to see if it solves the problem.
