<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>
|
|
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 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>
|
|
