systemd Developer Lennart Poettering lennart@poettering.net systemd.automount 5 systemd.automount systemd automount configuration files systemd.automount 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.unit5 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 file paths they reflect. 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.unit5. For each automount unit file a matching mount unit file (see systemd.mount5 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. Automount units may either be configured via unit files, or via /etc/fstab (see fstab5 for details). For details how systemd parses /etc/fstab see systemd.mount5. 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 following: Where= Takes an absolute path of a directory of the automount point. If the automount point is not existing at time of the automount point is installed it is created. This string must be reflected in the unit file name. (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. Defaults to 0755. systemd8, systemctl8, systemd.unit5, systemd.mount5, mount8, automount8
