  57                 <para><filename>systemd-remount-fs.service</filename>
  58                 is an early-boot service that applies mount options
  59                 listed in
  60                 <citerefentry><refentrytitle>fstab</refentrytitle><manvolnum>5</manvolnum></citerefentry>
  61                 to the root file system, the <filename>/usr</filename>
  62                 file system and the kernel API file systems. This is
  63                 required so that the mount options of these file
  64                 systems -- which are pre-mounted by the kernel, the
  65                 initial RAM disk, container environments or system
  66                 manager code -- are updated to those listed in
  67                 <filename>/etc/fstab</filename>. This service ignores
  68                 normal file systems and only changes the root file
  69                 system (i.e. <filename>/</filename>),
  70                 <filename>/usr</filename> and the virtual kernel API
  71                 file systems such as <filename>/proc</filename>,
  72                 <filename>/sys</filename> or
  73                 <filename>/dev</filename>. This service executes no
  74                 operation if <filename>/etc/fstab</filename> does not
  75                 exist or lists no entries for the mentioned file
  76                 systems.</para>
