<H2>DESCRIPTION</H2>
<P>
systemd-remount-fs.service
is an early boot service that applies mount options listed in
<B><A HREF="/cgi-bin/man/man2html?5+fstab">fstab</A></B>(5), or gathered from the partition table (when
<B><A HREF="/cgi-bin/man/man2html?8+systemd-gpt-auto-generator">systemd-gpt-auto-generator</A></B>(8)
is active) to the root file system, the
/usr
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
/etc/fstab
and the other sources. This service ignores normal file systems and only changes the root file system (i.e.
/),
/usr, and the virtual kernel API file systems such as
/proc,
/sys
or
/dev. This service executes no operation if no configuration is found (/etc/fstab
does not exist or lists no entries for the mentioned file systems, or the partition table does not contain relevant entries).

Note:
systemd-remount-fs.service
is usually pulled in by
<B><A HREF="/cgi-bin/man/man2html?8+systemd-fstab-generator">systemd-fstab-generator</A></B>(8), hence it is also affected by the kernel command line option
<I>fstab=</I>, which may be used to disable the generator. It may also pulled in by
<B><A HREF="/cgi-bin/man/man2html?8+systemd-gpt-auto-generator">systemd-gpt-auto-generator</A></B>(8), which is affected by
<I>systemd.gpt_auto</I>
and other options.
