It definitely feels like a bug - for an interface supporting
autoselect such as wm0 running
 "ifconfig ${if} none"
explicitly locks autoselect off and effectively downs the interface

So sysinst needs to be taught how to handle such interfaces. I don't
have a machine with ne0 to hand, but could someone with one confirm
whether this:
- Actually downs the interface (On a running system run 'ifconfig ne0
none' and see if the network stops)
- If the above doesn't stop the network, run sysinst and try to
configure the network and see if it works
I think it should be fixed whetever the case, but its nice to add
additional information to the PR for future historians :-p
