mount attaches a file system to the file system hierarchy at
the mount_point, which is the pathname of a
directory. If
mount_point has any contents prior to the mount
operation,
these are hidden until the file system is unmounted.
umount unmounts a currently mounted file system,
which may
be specified either as a mount_point or as
special, the
device on which the file system resides.
The table of currently mounted file systems can be
found by
examining the mounted file system information file.
This is
provided by a file system that is usually
mounted on
/etc/mnttab. The mounted file system
information is
described in mnttab(4). Mounting a file system adds an
entry
to the mount table; a umount removes an entry
from the
table.
When invoked with both the special and mount_point
argu-
ments and the -F option, mount validates all
arguments
except for special and invokes the appropriate
FSType-
specific mount module. If invoked with no arguments,
mount
lists all the mounted file systems recorded in the
mount
table, /etc/mnttab. If invoked with a partial
argument list
(with only one of special or mount_point, or
with both
special or mount_point specified but not FSType),
mount
will search /etc/vfstab for an entry that will
supply the
missing arguments. If no entry is found, and the
special
argument starts with "/", the default local file
system
type specified in /etc/default/fs will be used.
