I don't like the syntax, and in general I'd like hostname.if over time become a
list of arguments to pass on to ifconfig with no magic whatsoever attached, but
I like the relative KISS approach of this.
Alternatively, one could pass sth like "linkless" or "nolink" (or probably
something better), as a parameter to ifconfig, causing it to not process any
further arguments if the interface already has link status active.
