Definitely possible. However, any suggestions on how to avoid stepping
on the toes of other abusers of ifAlias, or is ladvd simply ignoring
this?

We definitely want this information easily accessible through
networkctl, so maybe we won't need to touch ifAlias (though I'm
absolutely not opposed to the idea as long as we don't gratuitously
break other users).

Cheers,
