is an early-boot service that applies mount options
listed in
<a href="fstab.html"><span class="citerefentry"><span class="refentrytitle">fstab</span>(5)</span></a>
to the root file system, the <code class="filename">/usr</code>
file system and the kernel API file systems. This is
required so that the mount options of these file
systems -- which are pre-mounted by the kernel, the
initial RAM disk, container environments or system
manager code -- are updated to those listed in
<code class="filename">/etc/fstab</code>. This service ignores
normal file systems and only changes the root file
system (i.e. <code class="filename">/</code>),
<code class="filename">/usr</code> and the virtual kernel API
file systems such as <code class="filename">/proc</code>,
<code class="filename">/sys</code> or
<code class="filename">/dev</code>. This service executes no
operation if <code class="filename">/etc/fstab</code> does not
exist or lists no entries for the mentioned file
systems.</p><p>For a longer discussion of kernel API file
systems see <a class="ulink" href="http://www.freedesktop.org/wiki/Software/systemd/APIFileSystems" target="_top">API
