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 <filename>/etc/fstab</filename>. This service ignores normal file systems and only changes the root file system (i.e. <filename>/</filename>), <filename>/usr</filename> and the virtual kernel API file systems such as <filename>/proc</filename>, <filename>/sys</filename> or <filename>/dev</filename>. This service executes no operation if <filename>/etc/fstab</filename> does not exist or lists no entries for the mentioned file systems.</para> <para>For a longer discussion of kernel API file systems see <ulink url="http://www.freedesktop.org/wiki/Software/systemd/APIFileSystems">API File Systems</ulink>.</para> </refsect1> <refsect1> <title>See Also</title> <para> <citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry>, <citerefentry project='man-pages'><refentrytitle>fstab</refentrytitle><manvolnum>5</manvolnum></citerefentry>, <citerefentry project='man-pages'><refentrytitle>mount</refentrytitle><manvolnum>8</manvolnum></citerefentry> </para> </refsect1> </refentry>
