<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 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>
