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.
Note that automount units are separate from the mount itself, so you should not set After= or Requires= for mount dependencies here. For example, you should not set After=network-online.target or similar on network filesystems. Doing so may result in an ordering cycle.
Note that automount support on Linux is privileged, automount units are hence only available in the system service manager (and root's user service manager), but not in unprivileged user's service manager.
Implicit Dependencies¶The following dependencies are implicitly added:
Default Dependencies¶The following dependencies are added 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:
