When I rebase and I need the old HEAD around I do something like this:
$ git checkout $branch_to_rebase
$ ver=${branch_to_rebase##*-}
$ git checkout -b ${branch_to_rebase%-${ver}}-$((ver+1))
$ git rebase ...
or like this:
$ git checkout $branch_to_rebase
$ git branch ${branch_to_rebase}-$(date +%Y-%m-%d)
$ git rebase ...
Either way I retain the old HEAD with some name. This requires
discipline, so scripting it is useful. But if you want discipline then
you want git to know that "for this branch, don't prune/gc old HEADs
orphaned after rebases" and "push the rebase history for this branch".
