Hmmm...  Strange.  I thought I had fixed that in the template and had
tested it with a gen-3 container build under a gen-2 container build
from my gen-1 VM.  Check /etc/sysconfig/network-scripts/ifcfg-eth0 for
"dhcp".  I'll look into that further.

That's something the SUSE gang needs to look at.  I'm not totally sure
zypper will support the cross arch option but, using a seed container
with an arch option set does work for building future containers of the
cross arch build.  Release should be doable, I just haven't looked at
it.

Yeah, if that can be done, it would be great.  Most of my past
experience was with SUSE on a zLinux mainframe and not much help here.
Maybe Thorsten over at SUSE might have some input on this particular
aspect.

Thorsten?
