Section: systemd.automount (5)
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 (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 (5).
For each automount unit file a matching mount unit file (see (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.
For details how systemd parses /etc/fstab see (5).
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:
- 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.
