Yes. Multiple ways. You can - just force that tree to be checked out: git-read-tree -m v2.6.11 git-checkout-cache -f -u -a this basically gets you the state at the time of v2.6.11, but you still don't have a _commit_ yet, so you'd have nothing to start actual development from. BE CAREFUL! Your "HEAD" is now pointing to something else than what you have checked out, so the next thing you want to do is fix that up. - now, you can commit that as a _parentless_ commit (ie an "Initial commit") on a new branch, with something like this: echo "Linux 2.6.11" | git-commit-tree $(git-write-tree) > .git/refs/heads/my-branch ln -sf .git/HEAD refs/heads/my-branch and off you go. The above just creates a commit of the tree (which is the v2.6.11 tree, since you did a "git-read-tree" on it), and uses the commit message "Linux 2.6.11"). It gives it no parents, and writes the result to the "my-branch" thing. It then makes HEAD point to that branch, which completes the thing, and now your tree is in a consistent state (ie HEAD matches what you have checked out, which matches v2.6.11) That's one way. You can do it sneakier too, if you want to, and create the branch first. In particular, you can do git-cat-file tag v2.6.11 which will print out that tag, which starts with: object c39ae07f393806ccf406ef966e9a15afc43cc36a type tree tag v2.6.11-tree ... and now you can just do use that tree directly, without even reading it in: head=$(echo "Linux 2.6.11" | git-commit-tree c39ae07f393806ccf406ef966e9a15afc43cc36a) echo $head > .git/refs/heads/my-branch which will give you the new branch. Now you can just do git checkout my-branch and you'll be there. That said, whatever you do you will eventually end up with a series of commits that are not related to the "normal" commits in the 2.6.12-rc2+ chain, and since they don't have a common point, git won't be able to merge them for you. Git will be able to _track_ them for you, but at some point you'll want to probably try to move them forward to the "rest" of the git history. And I'll warn you that that is not going to be entirely trivial, although Junio's "cherrypick" scripts should be useful as a way to automate it at least to some degree. This is why it would be so much easier if you could have started with a 2.6.12-rc2 or other "real" commit ;) Linus - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
