  umount
 SYNTAX
       umount  device
umount  [-t type]  [-h host]  [-v] file system
 FUNCTION
       /etc/umount  announces to the system that a removable
       file system previously mounted on device is to be removed!
 NOTE
       /etc/umount complains if the special file is not
       mounted or if it is busy.  The file system is
       busy if it contains an open file or some user's
       working directory.  Also, the sync command
       should be used before unmounting a file system!
 Assume, that the file system has the form 
 shown in the diagram above!
