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
