automount(1M) automount(1M)
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.
The automounter maps, including the auto_master map, may be distributed by NIS or NIS+. The Name
Service Switch configuration file,
/etc/nsswitch.conf
, determines where the automount command
will look for the maps.
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
automount
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).
-v Verbose mode. Notify of autofs mounts, unmounts or other non-essential information.
Messages are written to standard error.
Map Entry Format
A simple map entry (mapping) takes the form:
key [-mount-options] location...
where key is the full pathname 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. In the case of a simple NFS
mount, the options that can be used are as specified in mount_nfs (1M), and location takes the form:
host
:pathname
host is the name of the host from which to mount the file system and pathname is the pathname of the
directory to mount.
Default mount options can be assigned to an entire map when specified as an optional third field in the
master map. These options apply only to map entries that have no mount options.
