No, I meant the bzr tree; you mentioned explicitly setting up a bzr tree
for tracking Linus' tree.

Yep, I've been using both git (well, cogito) and bzr for a few months
now.  I've been impressed w/ the speed of both.  With bzr 0.0.7, commits
and diffs on a 2.4 kernel tree took a few seconds on my (rather slow)

I realize that; I was interested in a bzr tree that tracks upstream,
regardless, for measuring both bzr and git for my own purposes.

Yea, that's what I'd like to know about.  I guess this means you haven't
