Hello Sebastian,

Thanks for the pointers. Unfortunately it is unclear where the
specification should be used.

What is the spec good for on EFI systems where BootOrder and Boot####
variables define what is to be booted?

Do you want to replace extlinux/ ?
Do you expect GRUB to consider the entries when building grub.cfg?

How will the entries be created? Hopefully there is some code to do the job.

Best regards

Heinrich
