    <title>Description</title>

    <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>

    <para>If no command is passed, <command>status</command> is
    implied.</para>
