That's OK, as the main thing is the tests would tell you relative boot 
times.  (i.e. today's rawhide is faster/slower than yesterdays).

But, to the horrible 15 minute performance I saw with f8t1 under qemu- 
does that fall into the issue you mentioned?  I.e. are those debugging 
features turned on in f8t1?  how about f8t2?  What is the quickest way 
to determine if they are turned on or not?
