<title>Description</title>
|
|
|
|
<para>A unit configuration file whose name ends in
|
|
<literal>.mount</literal> 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 project='man-pages'><refentrytitle>mount</refentrytitle><manvolnum>8</manvolnum></citerefentry>
|
|
program is executed in, and in
|
|
<citerefentry><refentrytitle>systemd.kill</refentrytitle><manvolnum>5</manvolnum></citerefentry>,
|
|
which define the way the processes are terminated, and in
|
|
<citerefentry><refentrytitle>systemd.resource-control</refentrytitle><manvolnum>5</manvolnum></citerefentry>,
|
|
which configure resource control settings for the processes of the
|
|
service.</para>
|
|
|
|
<para>Note that the options <varname>User=</varname> and
|
|
<varname>Group=</varname> are not useful for mount units.
|
|
systemd passes two parameters to
|
|
<citerefentry project='man-pages'><refentrytitle>mount</refentrytitle><manvolnum>8</manvolnum></citerefentry>;
|
|
the values of <varname>What=</varname> and <varname>Where=</varname>.
|
|
When invoked in this way,
|
|
<citerefentry project='man-pages'><refentrytitle>mount</refentrytitle><manvolnum>8</manvolnum></citerefentry>
|
|
does not read any options from <filename>/etc/fstab</filename>, and
|
|
must be run as UID 0.</para>
|
|
|
|
<para>Mount units must be named after the mount point directories they control. Example: the mount point <filename
|
|
index="false">/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>. Note that mount
|
|
units cannot be templated, nor is possible to add multiple names to a mount unit by creating additional symlinks to
|
|
it.</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>Mount points created at runtime (independently of unit files
|
|
or <filename>/etc/fstab</filename>) will be monitored by systemd
|
|
and appear like any other mount unit in systemd. See
|
|
<filename>/proc/self/mountinfo</filename> description in
|
|
<citerefentry project='man-pages'><refentrytitle>proc</refentrytitle><manvolnum>5</manvolnum></citerefentry>.

|
|
<para>Some file systems have special semantics as API file systems
|
|
for kernel-to-userspace and userspace-to-userspace interfaces. Some
|
|
of them may not be changed via mount units, and cannot be
|
|
disabled. For a longer discussion see <ulink

iSCSI), in which case <option>_netdev</option> may be added to the mount option string of the unit, which forces

<para>Mount units may either be configured via unit files, or via

|

<citerefentry project='man-pages'><refentrytitle>fstab</refentrytitle><manvolnum>5</manvolnum></citerefentry>

for details). Mounts listed in <filename>/etc/fstab</filename>
|
|
will be converted into native units dynamically at boot and when
|
|
the configuration of the system manager is reloaded. In general,
|
|
configuring mount points through <filename>/etc/fstab</filename>
|
|
is the preferred approach. See

is detected by <command>systemd-fstab-generator</command> and the options

are transformed so that systemd fulfills the job-control implications of

that option. Specifically <command>systemd-fstab-generator</command> acts

prepended to the option list, and <literal>fg,nofail</literal> was appended.

<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
