Hmm. [greps GENERIC...] No, I don't. I figured that since pfctl was
working I was ok there, but I think it loads the module dynamicly. I can see
that if pfsync needs a static build it may rely on pf and pflog being static
also. I'll try that now and report.

Trust the computer industry to shorten Year 2000 to Y2K. It was this
thinking that caused the problem in the first place.
