NAME
       systemd.automount - Automount unit configuration

SYNOPSIS
       automount.automount

DESCRIPTION
       A unit configuration file whose name ends in ".automount" encodes
       information about a file system automount point controlled and
       supervised by systemd.

       This man page lists the configuration options specific to this unit
       type. See systemd.unit(5) for the common options of all unit
       configuration files. The common configuration items are configured in
       the generic [Unit] and [Install] sections. The automount specific
       configuration options are configured in the [Automount] section.

       Automount units must be named after the automount directories they
       control. Example: the automount point /home/lennart must be configured
       in a unit file home-lennart.automount. For details about the escaping
       logic used to convert a file system path to a unit name see
       systemd.unit(5).

       For each automount unit file a matching mount unit file (see
       systemd.mount(5) for details) must exist which is activated when the
       automount path is accessed. Example: if an automount unit
       home-lennart.automount is active and the user accesses /home/lennart
       the mount unit home-lennart.mount will be activated.

       Automount units may be used to implement on-demand mounting as well as
       parallelized mounting of file systems.

AUTOMATIC DEPENDENCIES
       If an automount unit is beneath another mount unit in the file system
       hierarchy, both a requirement and an ordering dependency between both
       units are created automatically.

       An implicit Before= dependency is created between an automount unit and
       the mount unit it activates.

       Automount units acquire automatic Before= and Conflicts= on
       umount.target in order to be stopped during shutdown, unless
       DefaultDependencies=no is set.

FSTAB
       Automount units may either be configured via unit files, or via
       /etc/fstab (see fstab(5) for details).

       For details how systemd parses /etc/fstab see systemd.mount(5).

       If an automount point is configured in both /etc/fstab and a unit file,
       the configuration in the latter takes precedence.

OPTIONS
       Automount files must include an [Automount] section, which carries
       information about the file system automount points it supervises. The
       options specific to the [Automount] section of automount units are the
       following:

       Where=
	   Takes an absolute path of a directory of the automount point. If
	   the automount point does not exist at time that the automount point
	   is installed, it is created. This string must be reflected in the
	   unit filename. (See above.) This option is mandatory.

       DirectoryMode=
	   Directories of automount points (and any parent directories) are
	   automatically created if needed. This option specifies the file
	   system access mode used when creating these directories. Takes an
	   access mode in octal notation. Defaults to 0755.

       TimeoutIdleSec=
	   Configures an idle timeout. Once the mount has been idle for the
	   specified time, systemd will attempt to unmount. Takes a unit-less
	   value in seconds, or a time span value such as "5min 20s". Pass 0
	   to disable the timeout logic. The timeout is disabled by default.
