Re: Cloning a remote tag without using git-fetch-pack directly?

Some quick additional thoughts.

Someone fetching v2.6.12 to build on it today is probably not planning
to run "git fetch origin" to fetch the same tag tomorrow.  So

	git init linux-2.6
	cd linux-2.6
	git remote add origin ~/src/linux-2.6
	git fetch origin refs/tags/v2.6.12

or even "...; git fetch ~/src/linux-2.6 refs/tags/v2.6.12" could be
closer to what is needed.

If for some reason you do want to track how the remote v2.6.12 tag
evolves, "git remote" has a funny way to do that:

	git remote add --mirror=fetch -ttags/v2.6.12 origin ~/src/linux.2.6

The documentation calls the argument to -t "<branch>", but in mirror
mode it is actually a refspec relative to refs/.

With luck (depending on what you are looking to do),
git-new-workdir[1] or "git archive --remote" could also be helpful.

Jonathan
