  29 .SH "DESCRIPTION"
  30 .PP
  31 systemd\-remount\-fs\&.service
  32 is an early\-boot service that applies mount options listed in
  33 \fBfstab\fR(5)
  34 to the root file system, the
  35 /usr
  36 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
  37 /etc/fstab\&. This service ignores normal file systems and only changes the root file system (i\&.e\&.
  38 /),
  39 /usr
  40 and the virtual kernel API file systems such as
  41 /proc,
  42 /sys
  43 or
  44 /dev\&. This service executes no operation if
  45 /etc/fstab
  46 does not exist or lists no entries for the mentioned file systems\&.
