<div dir="ltr">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 <a href="http://www.calculate-linux.org/boards/15/topics/26673">http://www.calculate-linux.org/boards/15/topics/26673</a>, 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.<div class="gmail_extra"><br><div class="gmail_quote">On Thu, Nov 10, 2016 at 12:35 PM, Petr Vobornik <span dir="ltr"><<a href="mailto:pvoborni@redhat.com" target="_blank">pvoborni@redhat.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div class="gmail-m_7865422996299277815HOEnZb"><div class="gmail-m_7865422996299277815h5">On 11/09/2016 12:53 PM, Prasun Gera wrote:<br>

to help.<br>

But based on the description it seems that it didn't even get to step<br>
where IPA is started.<br>
