>Description:

	"umount -f" option does not work. manual page says:
********8
NAME
     umount - unmount file systems

SYNOPSIS
     umount [-fv] special | node
     umount -a [-fv] [-h host] [-t ufs | lfs | external_type]

DESCRIPTION
     The umount command calls the unmount(2) system call to remove a special
     device or the remote node (rhost:path) from the file system tree at the
     point node. If either special or node are not provided, the appropriate
     information is taken from the fstab(5) file.

     The options are as follows:

     -a      All of the file systems described in fstab(5) are unmounted.

     -f      The file system is forcibly unmounted.  Active special devices
             continue to work, but all other files return errors if further
             accesses are attempted.  The root file system cannot be forcibly
             unmounted.
********8

>How-To-Repeat:

mount test-server:/home/src/DPSS  /usr/local/DPSS
cd /usr/local/DPSS
# umount /usr/local/DPSS
umount: /usr/local/DPSS: Device busy
# umount -f /usr/local/DPSS
umount: /usr/local/DPSS: Device busy
# umount -f test-server:/home/src/DPSS
umount: /usr/local/DPSS: Device busy

 In the previous versions of 'mount' included with FreeBSD the 'MNT_FORCE'
 flag (-f) was ignored, but this has been resolved in current versions.  I
 would suggest that you upgrade to a newer version of FreeBSD if you are
 still affected by this problem.
