<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>
