systemd-remount-fs.service, systemd-remount-fs — Remount root and kernel file systems
systemd-remount-fs.service
/usr/lib/systemd/systemd-remount-fs
systemd-remount-fs.service
is an early-boot service that applies mount options
listed in
fstab(5)
to the root file system, the /usr
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 /etc/fstab
. 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 /etc/fstab
does not
exist or lists no entries for the mentioned file systems.
