Hi,
is there a reason why efibootguard currently does not set the efi
variable `LoaderDevicePartUUID`[1]?
First time I hear about, possibly other contributors as well.
Where does this var come from? Only from systemd? It's not part of the
UEFI spec. Does grub-efi or other bootloaders set it as well?
Seems to be a systemd-only show and, no, grub does not join it.
Also that spec is a bit unclear /wrt what type this variables should
have. Very likely EFI_VARIABLE_BOOTSERVICE_ACCESS +
EFI_VARIABLE_RUNTIME_ACCESS. But also EFI_VARIABLE_NON_VOLATILE? I would
assume not, and I hope so as well - to avoid writing the variable
storage needlessly.
Problem: Will likely not work with U-Boot as this stage is that one
comes without UEFI runtime services IIUC.

we will deactivate `systemd-gpt-auto-generator` to avoid the error
messages during boot up.
What are distributions doing? Most of them are on grub by default and
should see the same issue.
The systemd-gpt-auto-generator only runs if `root=`[3] is not set in the
commandline. So most distributions do not see the message.
