This would mean --interface=X would either take ethN or bondN, if we
also support the bonding case, as opposed to a freeform string.
If you allow for --interface=X:Y then this would allow for the IPalias
support discussed yesterday
(eg: --interface=eth0:1 --ip=x.x.x.x --netmask=x.x.x.x)
this should generate a standard ifcfg file under
/etc/sysconfig/network-scripts but with a name like ifcfg-eth0:1
