automount - configure mount points for autofs
] mount-point map-type
program is used to configure a mount point for
autofs, the inlined Linux automounter. automount
taking a base mount-point
file, and using these
(combined with other options
) to automatically mount filesystems
within the base mount-point
when they are accessed in any way.
The filesystems are then autounmounted after a period of inactivity.
- -p, --pid-file
Write the pid of the daemon to the specified file.
- -t, --timeout
Set the minimum timeout, in seconds, until directories are unmounted.
The default is 5 minutes. Setting the timeout to zero disables
- -v, --version
Display the version number, then exit.
takes at least three arguments. Mandatory arguments
. Both mandatory
and optional arguments are described below.
Base location for autofs-mounted filesystems to be attached. This is a
directory name which must already exist.
Type of map used for this invocation of automount. The following are
valid map types:
The map is a regular text file.
The map is an executable program, which is passed a key on the command
line and returns an entry on stdout if successful.
The map is a NIS (YP) database.
The map is a NIS+ database.
The map is a hesiod database whose
entries are used for maps.
map names are of the form [servername:]basedn, where the optional
servername is the name of the LDAP server to query, and basedn is
the DN to do a subtree search under. Entries are automount objects in
the specified subtree, where the cn attribute is the key (the wildcard
key is "/"), and the automounterInformation attribute contains the
information used by the automounter. Documentation on the schema
used by this module is available online at
- format Format of the map data; currently the only formats
recognized are sun, which is a subset of the Sun automounter map
format, and hesiod, for hesiod filesys entries. If the format is
left unspecified, it defaults to sun for all map types except
Location of mapfile to use. This is an absolute UNIX pathname in the case
for maps of types file or program, and the name of a database
in the case for maps of type yp, nisplus, or hesiod.
Any remaining command line arguments without leading dashes (-) are
taken as options (-o) to mount. Arguments with leading
dashes are considered options for the maps.
If the automount
daemon catches signal USR1, it will unmount all
currently unused autofs-mounted filesystems and continue running
(forced unmount.) If it catches signal USR2 it will unmount all
unused autofs-mounted filesystems and exit if all filesystems were
unmounted. Busy filesystems will not be unmounted.
A whole slew of missing desirable features (see TODO
The documentation leaves a lot to be desired.
