SYSTEMD.AUTOMOUNT(5)systemd.automountSYSTEMD.AUTOMOUNT(5)NAMEsystemd.automount - Automount unit configuration
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
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.
If an automount point is beneath another mount point in the file system
hierarchy, a dependency between both units is created automatically.
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.
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
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.
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.
