	If I understand correctly that we would add
		'cd usr.sbin/user ; make default-group'
	to the end of the 'make distribution' target in etc/Makefile?

	While that target is a very flexible method of ensuring the
	'users' group could be added to any arbitrary group file, it
	does seem to make the process of finding out what /etc/group
	will contain from a source tree rather opaque.
