* Remove the OS specific bits, since NetBSD isn't interested in

porting this stuff back.

* Test /etc/motd for writability before trying to update it. This is
especially useful when /etc/ is mounted ro, like on a diskless boot.
(Thanks to phk for the idea on this one.)

* Make the "updating" message reflect what actually happens.
