wellwell, we also were apes for ages but does not mean that we stay behaving
like them and if some still does so it is also never to late to change
"ifconfig nic -alias" is obviously a wired and confusing behaviour and should
firstable do what it says, remove an alias and not the first IP address even
if it can be seen as an alias too. Logic would exist when ifconfig nic -alias
removes all aliases (or perhaps first of them) but not one by one starting
with the first ip. Then when there is no other alias left it should better
ask if removing the Ip address is really desired since it is essential to
have one. rmuser and other utilities also ask such kind of questions for less
then already beeing here there is more, ifconfig nic alias does not return
anything at all and ifconfig nic -alias on a nic w/o ip returns "can't assign
requested address" ...
