Yes, from my experiments, it gets stuck at some point where it has to start
avahi. And it fails to start it because it is dependent on something that
is not started yet (which is started when sssd is started). Googling for
that error pointed took me to, which seems to be
somewhat related I think. I'll post the journal messages soon. Is there
some sort of a systemd diff utility which can compare the start sequence of
services from two different systems ? Since my replica is on 7.2, which
afaik works fine, doing a diff between the two might highlight if something
has changed in the start sequence.
