Right, as soon as you start renaming the concept of a unit number can so easily
fade away that it's not worth the complexity trying to manage it.
# ifconfig tun0 name sillytun
I suddenly have no unit number because there's not such a constraint on names,
and imposing one would seem to be a bit weird. At some point, you converge on
restricting renames to maintaining the common prefix so that, e.g., tun0 ->
openvpn0 (bad example, but you can see where I'm going with this) wouldn't be
be possible because you don't want to maintain the arbitrary "openvpn" or
whatever unr space as well.
