disk space : USED+FREE=TOTAL?

[discussion on why USED+FREE space less than TOTAL...]

								   Currently
	   the only supported way I know to reorganize is the use dump/newfs/
	   restore.

There's another (easier) way, that doesn't require the fs to be
rebuilt:

	(single user mode)
	# mount /usr
	# cp /usr/etc/tunefs /tunefs
	# umount -a
	# /tunefs -m 2 /dev/rz1g
	# /tunefs -m 2 /dev/rz1h
		...
	# mount -a -t ufs

This changes the minimum amount of free space from the default (10
percent) to a more adequate [in a disk-space-starved environment, like
ours :-(] 2% (that's the number 2 in the /tunefs commands).
