busybox reboot/unmount issue

[Kumar Gala]

With a build of a recent busybox snapshot I get the following on a  
reboot:

# reboot
# BusyBox v1.1.1-pre0 (2006.02.27-15:56+0000) multi-call binary

Usage: umount [flags] FILESYSTEM|DIRECTORY

Unmount file systems

Flags:
         -a      Unmount all file systems
         -r      Try to remount devices as read-only if mount is busy
         -l      Lazy umount (detach filesystem)
         -f      Force umount (i.e., unreachable NFS server)
         -D      Do not free loop device (if a loop device has been  
used)

The system is going down NOW !!
Sending SIGTERM to all processes.
Please stand by while rebooting the system.
Restarting system.

The following is results of mount:

# mount
