.SH DESCRIPTION
 | 
						|
.PP
 | 
						|
A mounted file system is unmounted after the cache has been flushed to disk.
 | 
						|
A diskette should never be removed while it is mounted.
 | 
						|
If this happens, and is discovered before another diskette is inserted, the
 | 
						|
original one can be replaced without harm.
 | 
						|
Attempts to unmount a file system holding working directories or open files
 | 
						|
will be rejected with a \&'device busy\&' message.
 | 
						|

With the

.B \-s
 | 
						|
flag one can unmount swap space.
