+
+ <para>A unit configuration file whose name ends in
+ .mount encodes information about a file system mount
+ point controlled and supervised by systemd.</para>
+
+ <para>This man page lists the configuration options
+ specific to this unit type. See
+ <citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>
+ for the common options of all unit configuration
+ files. The common configuration items are configured
+ in the generic [Unit] and [Install] sections. The
+ mount specific configuration options are configured
+ in the [Mount] section.</para>
+
+ <para>Additional options are listed in
+ <citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry>.</para>
+
+ <para>Mount units must be named after the file paths
+ they reflect. Example: the mount point
+ <filename>/home/lennart</filename> must be configured
+ in a unit file
+ <filename>home-lennart.mount</filename>. For details
+ about the escaping logic used to convert a file system
+ path to a unit name see
+ <citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>.</para>
+ </refsect1>
+
+ <refsect1>
+ <title><filename>fstab</filename></title>
+
+ <para>Mount units may either be configured via unit
+ files, or via <filename>/etc/fstab</filename> (see
+ <citerefentry><refentrytitle>fstab</refentrytitle><manvolnum>5</manvolnum></citerefentry>
+ for details).</para>
+
+ <para>When reading <filename>/etc/fstab</filename> a
+ few special mount options are understood by systemd
+ which influence how dependencies are created for mount
+ points from <filename>/etc/fstab</filename>. If
+ <option>comment=systemd.mount</option> is specified as
+ mount option then systemd will create a dependency of
+ type <option>Wants</option> from either
+ <filename>local-fs.target</filename> or
+ <filename>remote-fs.target</filename>, depending
+ whether the file system is local or remote. If
+ <option>comment=systemd.automount</option> is set, an
+ automount unit will be created for the file system. See
+ <citerefentry><refentrytitle>systemd.automount</refentrytitle><manvolnum>5</manvolnum></citerefentry>
+ for details.</para>
+
+ <para>If a mount point is configured in both
+ <filename>/etc/fstab</filename> and a unit file the
+ configuration in the latter takes precedence.</para>

+ <title>Options</title>
+
+ <para>Mount files must include a [Mount] section,
+ which carries information about the file system mount points it
+ supervises. A number of options that may be used in
+ this section are shared with other unit types. These
+ options are documented in
+ <citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry>. The
+ options specific to the [Mount] section of service
+ units are the following:</para>
+
+ <variablelist>
+
+ <varlistentry>
+ <term><varname>What=</varname></term>
+ <listitem><para>Takes an absolute path
+ of a device node, file or other
+ resource to mount. See
+ <citerefentry><refentrytitle>mount</refentrytitle><manvolnum>8</manvolnum></citerefentry>
+ for details. If this refers to a
+ device node a dependency on the
+ respective device unit is
+ automatically created. (See
+ <citerefentry><refentrytitle>systemd.device</refentrytitle><manvolnum>5</manvolnum></citerefentry> for more information.)
+ This option is
+ mandatory.</para></listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term><varname>Where=</varname></term>
+ <listitem><para>Takes an absolute path
+ of a directory of the mount point. If
+ the mount point is not existing at
+ time of mounting it is created. This
+ string must be reflected in the unit
+ file name. (See above.) This option is
+ mandatory.</para></listitem>

+ <term><varname>Type=</varname></term>

+ </varlistentry>
+
+ <varlistentry>
+ <term><varname>DirectoryMode=</varname></term>
+ <listitem><para>Directories of mount

+ these directories. Defaults to
+ 0755.</para></listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term><varname>TimeoutSec=</varname></term>
+ <listitem><para>Configures the time to
+ wait for the mount command to
+ finish. If a comand does not exit
+ within the configured time the mount
+ will be considered failed and be shut
+ down again. All commands still running
+ will be terminated forcibly via
+ SIGTERM, and after another delay of
+ this time with SIGKILL. (See
+ <option>KillMode=</option> below.)
+ Takes a unit-less value in seconds, or
+ a time span value such as "5min
+ 20s". Pass 0 to disable the timeout
+ logic. Defaults to
+ 60s.</para></listitem>
