  66     <para><command>bootctl</command> checks, updates,
  67     installs or removes the boot loader from the current
  68     system.</para>
  69
  70     <para><command>bootctl status</command> checks and prints the
  71     currently installed versions of the boot loader binaries and
  72     all current EFI boot variables.</para>
  73
  74     <para><command>bootctl update</command> updates all installed versions of systemd-boot, if the current version is
  75     newer than the version installed in the EFI system partition. This also includes the EFI default/fallback loader at
  76     <filename>/EFI/BOOT/BOOT*.EFI</filename>. A systemd-boot entry in the EFI boot variables is created if there is no
  77     current entry. The created entry will be added to the end of the boot order list.</para>
  78
  79     <para><command>bootctl install</command> installs systemd-boot into the EFI system partition. A copy of
  80     systemd-boot will be stored as the EFI default/fallback loader at <filename>/EFI/BOOT/BOOT*.EFI</filename>. A
  81     systemd-boot entry in the EFI boot variables is created and added to the top of the boot order list.</para>
  82
  83     <para><command>bootctl remove</command> removes all installed
  84     versions of systemd-boot from the EFI system partition, and removes
  85     systemd-boot from the EFI boot variables.</para>
  86
  87     <para>If no command is passed, <command>status</command> is
