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), 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.
