Comment 11 for bug 2002226

@mate I agree with that concern w.r.t. sending random pe binaries to linux code path.

Separately in Mantic we are reverting zimg boot image format. Kernel itself fails to kexec it correctly. And mantic kexec tools do not support this image format correctly. Thus at this point grub 2.12 has best support for this anyway. And kernel itself & kexec-tools need work. If/when this gets re-enabled again, breaks will be used to ensure that grub2 of better than 2.12 is desired to get this going again, likely in 24.04.
