.SH "NAME"
systemd-remount-fs.service, systemd-remount-fs \- Remount root and kernel file systems
.SH "SYNOPSIS"
.PP
systemd\-remount\-fs\&.service
.PP
/lib/systemd/systemd\-remount\-fs
.SH "DESCRIPTION"
.PP
systemd\-remount\-fs\&.service
is an early boot service that applies mount options listed in
\fBfstab\fR(5)
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 \(em which are pre\-mounted by the kernel, the initial RAM disk, container environments or system manager code \(em are updated to those listed in
/etc/fstab\&. 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
/etc/fstab
does not exist or lists no entries for the mentioned file systems\&.
