What would be your typical workflow? Perhaps "git-pull + > make" on existing, but not latest source tree? Just a bog-standard "pull some stuff, do make, create a branch and put some patches on it, do make, switch to another branch, do make, etc". No advanced fiddling with git history, doing make on a subtree, etc.
