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

SYNOPSIS         top

       systemd-remount-fs.service

       /usr/lib/systemd/systemd-remount-fs

DESCRIPTION         top

       systemd-remount-fs.service is an early boot service that applies
       mount options listed in fstab(5), or gathered from the partition
       table (when systemd-gpt-auto-generator(8) is active) 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 configured
       in /etc/fstab and the other sources. 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 no configuration is found
       (/etc/fstab does not exist or lists no entries for the mentioned file
       systems, or the partition table does not contain relevant entries).

       For a longer discussion of kernel API file systems see API File
       Systems[1].

       Note: systemd-remount-fs.service is usually pulled in by
       systemd-fstab-generator(8), hence it is also affected by the kernel
       command line option fstab=, which may be used to disable the
       generator. It may also pulled in by systemd-gpt-auto-generator(8),
       which is affected by systemd.gpt_auto and other options.
