.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.
