<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>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>
