Good point. I guess I always build using the current kernel.

Certainly more rigorous, but falls down when the version.h file contains
several UTS_RELEASE lines (like Mandrake's kernel as delivered out of the

(Sigh) I guess the current implementation works OK as long as one builds the
kernel first.
