<title>Description</title>
|
|
|
|
<para>A unit configuration file whose name ends in
|
|
<filename>.mount</filename> 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>,
|
|
which define the execution environment the
|
|
<citerefentry><refentrytitle>mount</refentrytitle><manvolnum>8</manvolnum></citerefentry>
|
|
binary is executed in.</para>
|
|
|
|
<para>Mount units must be named after the mount point
|
|
directories they control. 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>
|
|
|
|
<para>Optionally, a mount unit may be accompanied by
|
|
an automount unit, to allow on-demand or parallelized
|
|
mounting. See
|
|
<citerefentry><refentrytitle>systemd.automount</refentrytitle><manvolnum>5</manvolnum></citerefentry>.</para>
|
|
|
|
<para>If an mount point is beneath another mount point
|
|
in the file system hierarchy, a dependency between both
|
|
units is created automatically.</para>
|
|
|
|
<para>Mount points created at runtime independent on
|
|
unit files or <filename>/etc/fstab</filename> will be
|
|
monitored by systemd and appear like any other mount
|
|
unit in systemd.</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 mount
|
|
units are the following:</para>

|
|
for details. If this refers to a
|
|
device node, a dependency on the
|
|
respective device unit is
|

automatically created. (See
