Public bug reported:
In distros/arch.py, the network configuration is created using
'DNS': str(tuple(info.get('dns-nameservers'))).replace(',', '')
However, when dns-nameservers is None, this causes both cloud-init and
cloud-init-local to fail with
failed run of stage init-local

The fix proposed in
https://bbs.archlinux.org/viewtopic.php?pid=1662566#p1662566 seems to
work for me, namely replacing the line with
'DNS': str(tuple(info.get('dns-nameservers'))).replace(',', '') if
info.get('dns-nameservers') != None else None
