bc70c1725f quoting << Martin_Blapp
-	Completly changed the internals of umount(8). We do three
	checks now to see if 'argv' is in the mounttable. It they
	all fail, we return to main and print a warning.

-	fixed the umount mount-order. The checks are rather complex
	to do this. Cause umount(8) should also be able to unmount
	several devices at once ('umount -a', 'umount -A',
	'umount /mnt /mnt2'), the mount-order get's important.
	I added checks to mark and unmark already unmounted devices.

- 	Various fixes with nfs-unmounts (no rpc-calls were done,
	or they were done although there was an existing mount).
	Since we allow overlay-mounts, we should also handle them
	properly.

-	Translate the deprecated nfs-syntax with '@' to ':' like
	mount_nfs does. The ':' syntax has now precedence, but '@'
	still works.

-	'umount -v' is now fixed for all cases and doesn't print
	garbage like two times the mountpoint etc.

-	removed non documented and useless umount '-F'.

-	hanged nfsmounts can now unmounted 'without' any problems.
	I've removed stat() and realpath() checks on the mountpoint.
	Instead we just do a realpath() on the basedir of the
	mountpath and add the dirname again.
	Implemented this as an idea from phk. But there are still
	vfs-restrictions if the nfs_mount is busy. If there are
	unwritten metadata on a hanged nfs-mount, and we modify
	nfs_vfsops.c to not return EBUSY, we get a deadlock :(
	The problem has now moved from userland to kernel.

-	removed the BUGS part from the umount(8) manpage.

-	Converted it to ANSI C (more than 60% of the code have
	changed).

adb378ce60 Use errx() instead of err() for malloc failures. -Wall. Do not dot
terminate errx() string. Remove unused #includes. Use .Tn for NFS.

d499a0ef65 Merge from Lite2.
- use new getvfsbyname() interface.
- new -A option, like -a except only mounted file systems are unmounted.

All non-cosmetic FreeBSD changes in umount.c, except ignoring of
realpath() failures, went away because they are done better in Lite2.
realpath() failures must be ignored so that non-pathnames like
"<above>:/foo" and "host:/bar" get as far as mount(2).

5974081cea From njw@cs.city.ac.uk (Nick Williams):
/sbin/umount does not return the correct exit status due to incorrect
logic in its internals.

Further, because of the nature of the code, you *cannot* use it to
umount a directory from a union mountpoint. Well, you can sometimes,
it depends on if the directory is at the top of the union stack or not :)
