I think I've addressed all the concerns you raised in the following patch. Can
you take a look and let me know if I've created any new ones? ;)
I have had to jump through a few hoops with regards to the SUSE -base kernel,
the kernel flavor, and an irritating build number... But I've been careful to
avoid changing variables for non-SUSE environments. There are a couple of
small places that could still happen (in _inspect_linux_kernel), but I think
there are enough safeguards in place that it shouldn't happen.
Thanks,
Mike
