This part of the copyright blurb stems from the GPL use recommendations: https://www.gnu.org/licenses/gpl-howto.en.html The concept appears to originate in times where version control was per file, instead of per tree, and was a way to glue the files together. Ultimately, we nowadays don't live in that world anymore, and this information is entirely useless anyway, as people are very welcome to copy these files into any projects they like, and they shouldn't have to change bits that are part of our copyright header for that. hence, let's just get rid of this old cruft, and shorten our codebase a bit.

|
<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>
