Wouldn't a better way of solving "full rebuild" issue be to use ccache or similar solution? Anyway, switching branches invalidates timestamps only on those files that change between branches -- it is to avoid unnecessary rebuilds. You can always clone with --reference, and use alternates (alternate object store). Just don't delete objects in repository that other repositories borrow from; GitHub uses refs/borrowers/ namespace for that, IIRC. HTH -- Jakub Narębski
