Agreed. For the reasons already discussed on this thread, using hostnames
with ipadm (and ifconfig) is problematic; we'd be better off without it.
For what it's worth, I happen to like using names whereever I can
rather than repeating magic numbers. Thus, I normally configure
systems with static IP addresses to have an entry in /etc/hosts
corresponding to the address I'm going to use, set up
/etc/nsswitch.conf to have 'files' listed first (as it Should Always
Be), and then use the name rather than the numeric address in
/etc/hostname.* and all the other configuration files.
This saves me from a lot of grief if I ever have to renumber the box.
In most cases, all I have to change is the /etc/hosts entry, and I'm
good to go. (Yes, some parts like /etc/resolv.conf are unusually
annoying about such things.)
Thus, I would like to manage statically addressed interfaces by name
if it's possible. And as Erik mentioned, if it's configured by name,
that same name should be used for all operations and shouldn't be
internally translated into something else.
I think the only question with a name is if there's more than
one address associated with it, do all of them get applied or
just one of them? I often work as you've described above and
when doing so, names used with interface address assignments
have always been unique.
