I could not find anything useful in the logs. But I might have hit a bug in either Python
or CentOS'/Fedora's gethostbyaddr() function:
https://mail.python.org/pipermail/python-list/2011-April/602796.html
Though the PTR record does point to an A record, not a CNAME.
The FQDN is the name for FreeIPA to use, yes. I am hitting the same error when I attempt
to use a local FQDN (set via hosts file) on the internal adapter.
Is there any way short of hacking the installer script to just skip this check?
Thank you,
Florian
