+    <title>Description</title>
+
+    <para><filename>systemd-remount-fs.service</filename> is an early boot service that applies mount options
+    listed in <citerefentry
+    project='man-pages'><refentrytitle>fstab</refentrytitle><manvolnum>5</manvolnum></citerefentry>, or
+    gathered from the partition table (when
+    <citerefentry><refentrytitle>systemd-gpt-auto-generator</refentrytitle><manvolnum>8</manvolnum></citerefentry>
+    is active) to the root file system, the <filename>/usr/</filename> 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
+    configured in <filename>/etc/fstab</filename> and the other sources. 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 no configuration is found
+    (<filename>/etc/fstab</filename> does not exist or lists no entries for the mentioned file systems, or
+    the partition table does not contain relevant entries).</para>
+
+    <para>For a longer discussion of kernel API file systems see
+    <ulink url="https://www.freedesktop.org/wiki/Software/systemd/APIFileSystems">API
+    File Systems</ulink>.</para>

+    <para>Note: <filename>systemd-remount-fs.service</filename> is usually pulled in by
+    <citerefentry><refentrytitle>systemd-fstab-generator</refentrytitle><manvolnum>8</manvolnum></citerefentry>,
+    hence it is also affected by the kernel command line option <varname>fstab=</varname>, which may be used
+    to disable the generator. It may also pulled in by
+    <citerefentry><refentrytitle>systemd-gpt-auto-generator</refentrytitle><manvolnum>8</manvolnum></citerefentry>,
+    which is affected by <varname>systemd.gpt_auto</varname> and other options.</para>
