NAME¶systemd.automount - Automount unit configuration
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). Note that automount units cannot be templated, nor is it possible to add multiple names to an automount unit by creating additional symlinks to its unit file.
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 in the "[Unit]" section.
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:
