automountd(8)

automountd8

Daemon handling autofs mount requests

Usage

automountd [-D name=value] [-i] [-m maxproc] [-o options] [-d] [-v]

Overview

The automountd daemon is responsible for handling autofs(4) mount requests, parsing maps, and mounting filesystems they specify. On startup, automountd forks into background and waits for kernel requests. When a request is received, automountd forks a child process. The child process parses the appropriate map and mounts filesystems accordingly. Then it signals the kernel to release blocked processes that were waiting for the mount.

-D

Define a variable.

-i

For indirect mounts, only create subdirectories if there are no wildcard entries. Without -i, automountd creates all the subdirectories it can. Users may not realize that the wildcard map entry makes it possible to access directories that have not yet been created.

-m maxproc

Limit the number of forked automountd processes, and thus the number of mount requests being handled in parallel. The default is 30.

-d

Debug mode: increase verbosity and do not daemonize.

-o options

Specify mount options. Options specified here will be overridden by options entered in maps or auto_master(5).

-v

Increase verbosity.

Exit status

The automountd utility exits 0 on success, and >0 if an error occurs.
