- <para><command>bootctl</command> checks, updates,
- installs or removes the boot loader from the current
- system.</para>
-
- <para><command>bootctl status</command> checks and prints the
- currently installed versions of the boot loader binaries and
- all current EFI boot variables.</para>
-
- <para><command>bootctl update</command> updates all installed
- versions of systemd-boot, if the current version is newer than the
- version installed in the EFI system partition. This also includes
- the EFI default/fallback loader at /EFI/BOOT/BOOT*.EFI. A
- systemd-boot entry in the EFI boot variables is created if there
- is no current entry. The created entry will be added to the end of
- the boot order list.</para>
-
- <para><command>bootctl install</command> installs systemd-boot into
- the EFI system partition. A copy of systemd-boot will be stored as
- the EFI default/fallback loader at /EFI/BOOT/BOOT*.EFI. A systemd-boot
- entry in the EFI boot variables is created and added to the top
- of the boot order list.</para>
-
- <para><command>bootctl remove</command> removes all installed
- versions of systemd-boot from the EFI system partition, and removes
- systemd-boot from the EFI boot variables.</para>
