I actually tried to get something like this together back in the BK days
and early in the SCO saga. It was pretty painful to try to find all the
historic trees and patches - they're all in different format, and some of
them are unreliable (ie CVS imports by people like Ted).
The good news is that git would be a lot more natural to the process of
trying to create a history, because you could basically import random
trees, and tag them as just independent trees, and then re-create the
history after-the-fact by trying to stitch them all together. And if you
find a new tree, you'd just re-stitch it - something that was very hard to
do with BK (and BK generally wouldn't help you with keeping multiple
independent trees around, and wouldn't generally accept the notion of
re-doing the histories and keeping various versions of the histories
So I've been thinking about trying to re-create some really old history
into git, but it's still a lot of work.. And obviously not very useful,
just interesting from an archeological standpoint.
