<title>Description</title>
<para><filename>systemd-remount-fs.service</filename>
is an early-boot service that applies mount options
listed in
<citerefentry><refentrytitle>fstab</refentrytitle><manvolnum>5</manvolnum></citerefentry>
to the root file system, the <filename>/usr</filename>
file system and the kernel API virtual 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 <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>
