If you configure additional aliases on a NIC using yast2, they will be
started automatically when the interface is brought up during boot or with
``ifup ethN'' (where N is 0, 1, etc).  There's nothing special required.

I frequently manually add new IP addresses to NICs by editing the
appropriate ifcfg-eth* file, then doing ``ifup ethN'' which adds the IP
without going through the normal rigamorole that yast2 will do when
changing network parameters.

Rightful liberty is unobstructed action according to our will within
limits drawn around us by the equal rights of others. I do not add 'within
the limits of the law' because law is often but the tyrant's will, and
always so when it violates the rights of the individual.
