Details:

In adding GRUB boot entries for Xen on Arch Linux using grub-mkconfig
My distribution Xen package installs /boot/xen-$vernum.efi and
/boot/xen-$vernum.config

20_linux_xen picks these up as bootable Xen loaders for multiboot2,
and I end up with unbootable GRUB entries for them.

Could grub_file_is_not_garbage be expanded to include *.config?
http://git.savannah.gnu.org/cgit/grub.git/tree/util/grub-mkconfig_lib.in#n184

Would it be appropriate to add a file_is_not_efi and, or file_is_not_config
helper function in 20_linux_xen,
similar to file_is_not_sym
http://git.savannah.gnu.org/cgit/grub.git/tree/util/grub.d/20_linux_xen.in#n176

Happy to submit these as patches if suitable,
or take to distribution package level if not.


Cheers,
John
