NAME
mount, umount - mount and dismount file system
SYNOPSIS
/etc/mount [ special name [ -r ] ]
/etc/umount special
DESCRIPTION
Mount announces to the system that a removable file system is present
on the device special. The file name must exist already; it must be a
directory (unless the root of the mounted file system is not a direc‐
tory). It becomes the name of the newly mounted root. The optional
last argument indicates that the file system is to be mounted read-
only.
Umount announces to the system that the removable file system previ‐
ously mounted on device special is to be removed.
These commands maintain a table of mounted devices. If invoked without
an argument, mount prints the table.
Physically write-protected and magnetic tape file systems must be
mounted read-only or errors will occur when access times are updated,
whether or not any explicit write is attempted.
FILES
/etc/mtab: mount table
SEE ALSO
mount(2), mtab(5)
BUGS
Mounting file systems full of garbage will crash the system.
Mounting a root directory on a non-directory makes some apparently good
pathnames invalid.
