I believe so (the irrelevant part). But the functionality part of grubby picking
up /etc/sysconfig/kernel and making that kernel the default is not in Grub2 - so
not sure how that can be addressed.

Somehow the xen-kbdfront driver is not included in the initrd image
(I think) - and we end with anaconda but can't type anything.  I've been trying
to figure out how to inject said module in the install initrd to see if that is
really the problem but running in roadblocks (like xz 5.1.1alpha or 5.0.3 complains
about corrupt image, or I've no idea how to make driver disks).

Any ideas?
