/me tries to reconcile this statement with the kernel rip-up he's in
the middle of.

So we're already smaller than Ubuntu.  Size is one of the things we've
been told is key to adoption in the cloud.  If we're already smaller,
and Ubuntu is more widely adopted, I don't see that holding true.
What am I missing, or is the "we need a smaller kernel package" thing
somehow trying to pull the wool over my eyes?
