    <title>Description</title>

    <para><command>bootctl</command> can check the EFI boot loader status, list
    available entries, and install, update, or remove the
    <citerefentry><refentrytitle>sd-boot</refentrytitle><manvolnum>7</manvolnum></citerefentry>
    boot loader on the current system.</para>

    <para><command>bootctl status</command> shows the currently installed versions of
    the boot loader binaries and all current EFI boot variables.</para>

    <para><command>bootctl list</command> displays all configured boot loader entries.
    </para>

    <para><command>bootctl update</command> updates all installed versions of
    <citerefentry><refentrytitle>sd-boot</refentrytitle><manvolnum>7</manvolnum></citerefentry>,
    if the current version is newer than the version installed in the EFI system
    partition. This also includes the EFI default/fallback loader at
    <filename><replaceable>ESP</replaceable>/EFI/BOOT/BOOT*.EFI</filename>. 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
    <filename><replaceable>ESP</replaceable>/EFI/BOOT/BOOT*.EFI</filename>. 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>
