Yes, and even embedding this in the pack-file (or perhaps, the index, as a new index extension) is probably a good idea. > If we want to store also roots, we could either map > "commit sha-1 => generation number, roots set offset / id" (constant > length value)[*1*], or have gen-*.gen file with generation numbers > and roots, and gen-*.idx as index to that file. The thing is, the roots are almost never actually interesting. Very seldom do you have any issue with different commits having different roots. So I really don't think it's worth it, considering that it's also much more complicated than just adding a sequence number to each commit.
