Re: generate a diff against a specific tag in a remote branch

I currently have a copy of the kernel TuxOnIce git tree, and the
latest tag is 2.6.33.

I also have added linus tree as a remote branch
(git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git).

What I want to do is to make a patch of the TuxOnIce changes to apply
to the linus' 2.6.33. The problem is that the linus tree keeps
advacing, obviously, and is now at 2.6.34-rc1.

So what I've been trying to do is to make a diff against the 2.6.33
tag of linus' tree. Is this possible?

Probably. Try rebasing your TuxOnIce branch on the tag:

  $ git checkout -b temporary TuxOnIce
  $ git rebase v2.6.33

If it works out (you may have to correct some conflicts) during rebase,
the branch "temporary" can be used to generate a set of patches to
add TuxOnIce to a vanill 2.6.33 (by using git format-patch, for example).
