NAME
systemd-remount-fs.service, systemd-remount-fs - Remount root and
kernel file systems
SYNOPSIS
systemd-remount-fs.service
/usr/lib/systemd/systemd-remount-fs
DESCRIPTION
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 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.
For a longer discussion of kernel API file systems see API File
Systems[1].
