                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
