I saw some people being unhappy with the idea of interface rename
("once you're renamed it to foobar you don't know anymore if it's a
wm(4) or a tap(4), or possibly a bridge(4)") and I also like being
able to classify interfaces looking  at their name,
But I also see a need to be able to refer to them using a different name.
But this is different from a rename.

I really think the feature we want is "alias", not "rename".
