It also uses git, bzr and hg: https://github.com/bundlewrap/bundlewrap/blob/567b5f055067b1e23ea8081b24f1bebfdc44c541/bundlewrap/utils/scm.py#L10 these theoretically should be absolutised though there might be closure size concerns. There's also a use of 'stat': https://github.com/bundlewrap/bundlewrap/blob/567b5f055067b1e23ea8081b24f1bebfdc44c541/bundlewrap/utils/remote.py#L8 Possibly there are more things to absolutise.
