NAME

automount - install automatic mount points

SYNOPSIS

/usr/sbin/automount

[-f master-ﬁle][

-t duration ][-v]

DESCRIPTION

The

automount command installs autofs mount points and associates an

automount map with each

mount point. The

autofs ﬁlesystem monitors attempts to access directories within it and notiﬁes the

automountd daemon (see automountd (1M)). The daemon uses the map to locate a ﬁlesystem, which it

then mounts at the point of reference within the

autofs ﬁlesystem. You can assign a map to an

autofs mount using an entry in the /etc/auto_master

map or a direct map.

If the ﬁlesystem is not accessed within an appropriate interval (10 minutes by default), the

automountd

daemon unmounts the ﬁle system.

The ﬁle

/etc/auto_master

determines the locations of all

autofs mount points. By default, this ﬁle

contains the following entry:

# Master map for automounter

/net -hosts -nosuid,soft,nobrowse

The ﬁrst ﬁeld in the master ﬁle speciﬁes a directory on which an

autofs mount will be made, and the

second ﬁeld speciﬁes the automounter map to be associated with it. Mount options may be supplied as an

optional third ﬁeld in the entry. These options are used for any entries in the map that do not specify

mount options explicitly. The

automount command is usually run without arguments. It compares the

entries /etc/auto_master

with the current list of autofs mounts in /etc/mnttab and adds,

removes, or updates

autofs mounts to bring the /etc/mnttab up to date with the

/etc/auto_master. At boot time, it installs all

autofs mounts from the master map. Subsequently,

it may be run to install

autofs mounts for new entries in the master map or a direct map, or to perform

unmounts for entries that have been removed.

If the ﬁrst ﬁeld speciﬁes the directory as

/-, automount treats the second ﬁeld as the name of a direct

map. In a direct map, each entry associates the full path name of a mount point with a remote ﬁle system

to mount.

If the ﬁrst ﬁeld is a path name, the second ﬁeld names an indirect map or a special map (described

below). An indirect map contains a list of the subdirectories within the indicated directory. With an

indirect map, it is these subdirectories that are mounted automatically.

The automounter maps, including the auto_master map, may be distributed by NIS or LDAP. The Name

Service Switch conﬁguration ﬁle,

/etc/nsswitch.conf

, determines where the automount command

will look for the maps.

Options

automount recognizes the following options:

-f master-file Specify a local master ﬁle for initialization.

When the

-f option is used and the master ﬁle speciﬁed is not found, then auto-

mount defaults to /etc/auto_master and then to the NIS auto_master map.

-t duration Specify a duration , in seconds, that a ﬁle system is to remain mounted when not in

use. The default is 600 (10 minutes). The new duration value will apply to new

autofs mount points and their associated autofs mounts. Note that setting a

new duration does not affect any existing autofs mount points or associated

autofs mounts. In order for the new duration to take effect, an existing autofs

mount point must ﬁrst be unmounted, then remounted.

-v Verbose mode. Notify of autofs mounts, unmounts, or other non-essential infor-

mation. Messages are written to standard error.

Map Entry Format

A simple map entry (mapping) takes the form:

key [-mount-options] location...

automount(1M) automount(1M) where key is the full path name of the directory to mount when used in a direct map, or the simple name of a subdirectory in an indirect map. mount-options is a comma-separated list of mount options, and location specifies a file system from which the directory may be mounted.

automount(1M) automount(1M) it would allow automatic mounts in /config of any remote file system whose location could be specified as: hostname :/export/config/hostname Variable Substitution Client specific variables can be used within an automount map. For instance, if $HOST appeared within a map, automount would expand it to its current value for the client’s host name. Supported variables are: CPU The processor type. The possible values are: IA64, PA10, PA11, PA20. HOST The output of uname -n.

automount(1M) automount(1M) Direct Maps Entries in a direct map are associated directly with autofs mount points. Each key is the full path name of an autofs mount point. The direct map as a whole is not associated with any single directory. Since each direct map entry results in a new autofs mount, such maps should be kept short. If a directory contains direct map mount points, then an ls -l in the directory will force all the direct map mounts to occur.
