I've read about the ::1 problem in the archives. This problem
does not happen when I create new lo(4) interfaces. Maybe it has
been fixed silently?
The new diff (http://nedbsd.nl/~ppostma/if_loop.diff) removes the
loop option and includes it automatically when INET or INET6 is defined.
But I'm not really happy about how it attaches (we can't define mandatory
pseudo-devices? and would it be useful to add such functionality?).
I'm also not sure if everyone likes to go into this direction.
