## 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)](https://www.chedong.com/phpMan.php/man/fstab/5/markdown), or gathered from the partition table (when [**systemd-gpt-auto-generator**(8)](https://www.chedong.com/phpMan.php/man/systemd-gpt-auto-generator/8/markdown) 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)](https://www.chedong.com/phpMan.php/man/systemd-fstab-generator/8/markdown), 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)](https://www.chedong.com/phpMan.php/man/systemd-gpt-auto-generator/8/markdown), which is affected by
       _systemd.gpt_auto_ and other options.
