       bootctl - Control the firmware and boot manager settings

       bootctl [OPTIONS...] {COMMAND}

       bootctl can check the EFI boot loader status, list available boot
       loaders and boot loader entries, and install, update, or remove the
       systemd-boot(7) boot loader on the current system.

       The following options are understood:

           Path to the EFI System Partition (ESP). If not specified, /efi,
           /boot, and /boot/efi are checked in turn. It is recommended to
           mount the ESP to /boot, if possible.

       -p, --print-path
           This option modifies the behaviour of status. Just print the path
           to the EFI System Partition (ESP) to standard output and exit.

           Do not touch the firmware's boot loader list stored in EFI

           Do not pipe output into a pager.

       -h, --help
           Print a short help text and exit.

           Print a short version string and exit.

           Shows brief information about the system firmware, the boot loader
           that was used to boot the system, the boot loaders currently
           available in the ESP, the boot loaders listed in the firmware's
           list of boot loaders and the current default boot loader entry. If
           no command is specified, this is the implied default.

           Installs systemd-boot into the EFI system partition. A copy of
           systemd-boot will be stored as the EFI default/fallback loader at
           ESP/EFI/BOOT/BOOT*.EFI. The boot loader is then added to the top of
           the firmware's boot loader list.

           Updates all installed versions of systemd-boot(7), if the available
           version is newer than the version installed in the EFI system
           partition. This also includes the EFI default/fallback loader at
           ESP/EFI/BOOT/BOOT*.EFI. The boot loader is then added to end of the
           firmware's boot loader list if missing.

           Removes all installed versions of systemd-boot from the EFI system
           partition and the firmware's boot loader list.

           Shows all available boot loader entries implementing the Boot
           Loader Specification[1], as well as any other entries discovered or
           automatically generated by the boot loader.

       set-default ID, set-oneshot ID
           Sets the default boot loader entry. Takes a single boot loader
           entry ID string as argument. The set-oneshot command will set the
           default entry only for the next boot, the set-default will set it
           persistently for all future boots.

       On success, 0 is returned, a non-zero failure code otherwise.

       If $SYSTEMD_RELAX_ESP_CHECKS=1 is set the validation checks for the ESP
       are relaxed, and the path specified with --path= may refer to any kind
       of file system on any kind of partition.
