Is that an additional scenario though? With the git ref support patch,
users will be able to pass either a tarball (the tarball won't be deleted
so the user can reuse it) or a git ref (when running DTS from the
repository). What I wanted to know is how do you arrive at a setup where
you have a local directory that's not a git repository and you don't have a
tarball - i.e. how do you have a local non-repo directory without a tarball
(you have to get the local directory from somewhere, presumable a tarball)?
