  56                 a generator that translates

  58                 <citerefentry><refentrytitle>fstab</refentrytitle><manvolnum>5</manvolnum></citerefentry>
  59                 for details) into native systemd units early at boot
  60                 and when configuration of the system manager is
  61                 reloaded. This will instantiate mount and swap units

  65                 like a simple boolean, and the ordering information is
  66                 discarded. However, if the root file system is
  67                 checked, it is checked before all the other
  68                 file systems.</para>
