SYSTEMD-REMOUNT-FS.SERVICE(8)			    systemd-remount-fs.service

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), 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 initrd, 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
       be pulled in by systemd-gpt-auto-generator(8), which is affected by
       systemd.gpt_auto and other options.
