# autofs.conf(5)

automount(8) and automountd(8) configuration file

## NAME

**autofs.conf** – [automount(8)](/automount/8.md) and [automountd(8)](/automountd/8.md) configuration file

## DESCRIPTION

The **autofs.conf** file specifies various configuration options for [automount(8)](/automount/8.md) and [automountd(8)](/automountd/8.md).

**autofs.conf** consists of a series of lines, each of which may contain a line that sets a parameter, a comment, or a blank line.

A line that sets a parameter has the format:

*parameter*=*value*

A “#” is the comment character, and all characters from it to the end of line are ignored.

The parameters that are supported are:

- AUTOMOUNT\_TIMEOUT

  The number of seconds after which an automounted file system will be unmounted if it hasn't been referred to within that period of time.  The default is 1 hour (3600 seconds). This is equivalent to the **-t** option in [automount(8)](/automount/8.md).

- AUTOMOUNT\_VERBOSE

  TRUE or FALSE; if TRUE, [automount(8)](/automount/8.md) will print more detailed information about the actions it takes. This is equivalent to the **-v** option to [automount(8)](/automount/8.md).

- AUTOMOUNTD\_VERBOSE

  TRUE or FALSE; if TRUE, [automountd(8)](/automountd/8.md) will log to [syslogd(8)](/syslogd/8.md) more detailed information about the actions it takes. This is equivalent to the **-v** option to [automountd(8)](/automountd/8.md).

- AUTOMOUNTD\_NOBROWSE

  TRUE or FALSE; if TRUE, [automountd(8)](/automountd/8.md) will disable browsing of all maps. This is equivalent to the **-n** option to [automountd(8)](/automountd/8.md).

- AUTOMOUNTD\_TRACE

  The trace level for logging information about requests received by [automountd(8)](/automountd/8.md) from autofs, processing done for those requests, and replies sent to autofs. The default level of 0 causes no information to be logged; each higher value causes more information to be logged. This controls the same trace level that the **-T** option to [automountd(8)](/automountd/8.md) controls. The trace is logged to /var/log/system.log

- AUTOMOUNTD\_MNTOPTS

  A string containing a comma-separated list of mount options that will be applied, by default, to all mounts done by [automountd(8)](/automountd/8.md). The options for a particular mount can override these options. This controls the same options that the **-o** option to [automountd(8)](/automountd/8.md)

- AUTOMOUNTD\_NOSUID

  TRUE or FALSE; if TRUE, [automountd(8)](/automountd/8.md) will force all mounts to have the "nosuid" mount option set.

- AUTOMOUNTD\_ENV

  A string of the form

  *name*=*value*

  that causes the environment variable *name* to be set to the value *value* in [automountd(8)](/automountd/8.md). Environment variables can be referred to in map entries; the value of the environment variable is substituted for the reference to the variable. This is equivalent to the **-D** option to [automountd(8)](/automountd/8.md).
