Indeed. chunkfs looks interesting on that front. Val has that rare
combination of talents: being able to design and implement clever
new ideas *and* to be able to explain them coherently to the rest
of us.

Yep. When I first saw systemtap, I thought it looked like a great
idea, but was some way behind dtrace, which it appeared to just be
cloning. But the more I looked into it, I realised that systemtap had
the better design, and could potentially do a lot more. It was just
a matter of time before it caught up and overtook dtrace. It still
has some useability issues (particularly when, for example, trying to
trace a program on a production box without a C compiler), but it's
getting better all the time, and it's now an essential debugging tool
for me.
