  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
  75     versions of systemd-boot, if the current version is newer than the
  76     version installed in the EFI system partition. This also includes
  77     the EFI default/fallback loader at /EFI/Boot/boot*.efi. A
  78     systemd-boot entry in the EFI boot variables is created if there
  79     is no current entry. The created entry will be added to the end of
  80     the boot order list.</para>
  81
  82     <para><command>bootctl install</command> installs systemd-boot into
  83     the EFI system partition. A copy of systemd-boot will be stored as
  84     the EFI default/fallback loader at /EFI/Boot/boot*.efi. A systemd-boot
  85     entry in the EFI boot variables is created and added to the top
  86     of the boot order list.</para>
  87
  88     <para><command>bootctl remove</command> removes all installed
  89     versions of systemd-boot from the EFI system partition, and removes
  90     systemd-boot from the EFI boot variables.</para>
  91
  92     <para>If no command is passed, <command>status</command> is
