NAME

       systemd-remount-fs.service, systemd-remount-fs - Remount root and kernel file systems

SYNOPSIS

       systemd-remount-fs.service

       /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].
