| 23 | "<code class="literal">.automount</code>" encodes information about a file | |
| 24 | system automount point controlled and supervised by | |
| 25 | systemd.</p><p>This man page lists the configuration options specific to | |
| 26 | this unit type. See | |
| 27 | <a href="systemd.unit.html"><span class="citerefentry"><span class="refentrytitle">systemd.unit</span>(5)</span></a> | |
| 28 | for the common options of all unit configuration files. The common | |
| 29 | configuration items are configured in the generic [Unit] and | |
| 30 | [Install] sections. The automount specific configuration options | |
| 31 | are configured in the [Automount] section.</p><p>Automount units must be named after the automount | |
| 32 | directories they control. Example: the automount point | |
| 33 | <code class="filename">/home/lennart</code> must be | |
| 34 | configured in a unit file | |
| 35 | <code class="filename">home-lennart.automount</code>. For details about the | |
| 36 | escaping logic used to convert a file system path to a unit name | |
| 37 | see | |
| 38 | <a href="systemd.unit.html"><span class="citerefentry"><span class="refentrytitle">systemd.unit</span>(5)</span></a>.</p><p>For each automount unit file a matching mount unit file (see | |
| 39 | <a href="systemd.mount.html"><span class="citerefentry"><span class="refentrytitle">systemd.mount</span>(5)</span></a> | |
| 40 | for details) must exist which is activated when the automount path | |
| 41 | is accessed. Example: if an automount unit | |
| 42 | <code class="filename">home-lennart.automount</code> is active and the user | |
| 43 | accesses <code class="filename">/home/lennart</code> the mount unit | |
| 44 | <code class="filename">home-lennart.mount</code> will be activated.</p><p>Automount units may be used to implement on-demand mounting | |
| 45 | as well as parallelized mounting of file systems.</p><p>If an automount point is beneath another mount point in the | |
| 46 | file system hierarchy, a dependency between both units is created | |
| 47 | automatically.</p></div><div class="refsect1"><a name="idm140603569402144"></a><h2 id="fstab"><code class="filename">fstab</code><a class="headerlink" title="Permalink to this headline" href="#fstab">¶</a></h2><p>Automount units may either be configured via unit files, or | |

| 50 | for details).</p><p>For details how systemd parses | |

| 52 | <a href="systemd.mount.html"><span class="citerefentry"><span class="refentrytitle">systemd.mount</span>(5)</span></a>.</p><p>If an automount point is configured in both | |
| 53 | <code class="filename">/etc/fstab</code> and a unit file, the configuration | |
| 54 | in the latter takes precedence.</p></div><div class="refsect1"><a name="idm140603569395984"></a><h2 id="Options">Options<a class="headerlink" title="Permalink to this headline" href="#Options">¶</a></h2><p>Automount files must include an [Automount] section, which | |
| 55 | carries information about the file system automount points it | |

| 57 | automount units are the following:</p><div class="variablelist"><dl class="variablelist"><dt id="Where="><span class="term"><code class="varname">Where=</code></span><a class="headerlink" title="Permalink to this term" href="#Where=">¶</a></dt><dd><p>Takes an absolute path of a directory of the | |

| 59 | that the automount point is installed, it is created. This | |

| 64 | creating these directories. Takes an access mode in octal | |
| 65 | notation. Defaults to 0755.</p></dd></dl></div></div><div class="refsect1"><a name="idm140603573107840"></a><h2 id="See Also">See Also<a class="headerlink" title="Permalink to this headline" href="#See%20Also">¶</a></h2><p> | |
