Hi all,

Trying to boot Fedora using iPXE from GRUB [1], it does not work.
Following the manual how to add the boot menu item, the boot fails with
the "kernel too old" message.

This is probably caused due to iPXE kernel reporting its version as 1.0.0+:

$ file /boot/bfo.lkrn
/boot/bfo.lkrn: Linux kernel x86 boot executable bzImage, version 1.0.0+
(a937), RO-rootFS,

$ file /boot/vmlinuz-3.18.7-200.fc21.x86_64
/boot/vmlinuz-3.18.7-200.fc21.x86_64: Linux kernel x86 boot executable
bzImage, version 3.18.7-200.fc21.x86_64
(mockbuild at bkernel02.phx2.fedoraproject., RO-rootFS, swap_dev 0x5,
Normal VGA

Initially I reported the issue into RH Bugzilla [1], but laying there
without any response, I asked the same question in Grub's tracker [2].
Now the Grub developer asking me, how to detect the iPXE kernel. Could
you please provide me some hint?
