I don't speak for my employer in any way shape or form.  My comments
are my own and do not represent those of my employer.  <Insert random
other ways of saying I speak for me alone and not my employer>.  Fedora
is done in my spare time.

Besides, my employer is probably more concerned with the fact that
Fedora 9 Alpha (and likely Beta) doesn't even install on their class of
hardware because of Anaconda/HAL refusing to see the disks on Power6
and LPARs (as well as PS3).
