I cannot reproduce it on my instance: http://openqa.slindomansilla-vm.qa.suse.de/tests/2095

I will try to get logs from the production machine.

The installer is trying to get the hostname from install.inf, where an IP address is specified:

sysconfig/hostname_reader.rb:82 Got 192.168.112.10 from install.inf

Then, it tries to resolve that IP to get a name. That resolution fails, so a nil or an empty string (I'm not sure which one) is returned by Yast::NetHwDetection.ResolveIP. That results in the following log entry:

sysconfig/hostname_reader.rb:89 Got  after resolving IP from install.inf

But YaST tries to break that empty string (or nil) into a host and a domain part. Which is a nonsense and returns a nil host. Which makes YaST blow away.

I guess that #hostname_from_install_inf should return nil if install.inf contains an IP address that cannot be translated into a name. Imo, Knut, is that the case?

If so, I can fix it right away.
