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

.SH "SYNOPSIS"

.PP systemd-remount-fs.service

.PP /usr/lib/systemd/systemd-remount-fs

.SH "DESCRIPTION"

.PP systemd-remount-fs.service is an early boot service that applies mount options listed in [**fstab**(5)](/man/os/systemd/fstab.5), or gathered from the partition table (when [**systemd-gpt-auto-generator**(8)](/man/os/systemd/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).

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

.PP Note: systemd-remount-fs.service is usually pulled in by [**systemd-fstab-generator**(8)](/man/os/systemd/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)](/man/os/systemd/systemd-gpt-auto-generator.8), which is affected by *systemd.gpt\_auto* and other options.
