- allow mounting with "none" block device - allow unmounting by mountpoint - make VFS aware of file system process labels - allow m3_ca1 to use the full available message size - use *printf in u/mount(1), as mount(2) uses it already - fix reference leaks for some mount error cases in VFS

.SH DESCRIPTION
|
|
.PP
|
|
This command unmounts a file system identified by
|
|
.IR name .
|
|
This name may be either a block special file, or the path name of a mount
|
|
point.
|
|
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.
