I'm not maintaining bootchart, just -2. We're just different maintainers. Do you
have a bugreport handy?

Yes, I noticed that too. And I'd like to fix that, if possible.

I guess I'll take some time to see the "bootchart" package in Ubuntu -- which I
see now diverged enough to be considered something different :)

Scott, if bootchart2 upstream ACKs your (Ubuntu's) changes, would you agree to
find a common path to reduce the Deb-Ubu delta, and have a common package (or,
at least, a common basis)?
(I should probably also contact the bootchart Debian maintainer)
Thank you,
David
