It's [apparently] expecting you to use vi to create a named.conf
that will work, and showing you the contents of both the old
named.conf and the one found in 7.0-RELEASE. I'm not familiar
with freebsd-update (still using the old csup/buildworld routine)
but it sure look like mergemaster, more or less, except that
mergemaster not only allowed you to leave it until later and
do the merge "by hand" but also had a two-column "diff" with
a selector routine, so you could create a "merged" version
on-the-fly.
Is the box an important DNS server? What happens if you just
save the file as is and try and come back to it later? (YMMV,
standard disclaimer, and all that). if you've *never* edited
named.conf before, you'd probably be OK to just remove all the
current version stuff in favor of the 7.0-RELEASE stuff, *but*
generally all my boxen *have* been altered, so that wouldn't
work.
