Test if git clones (at specific revision) can be deterministic
#!/usr/bin/env bash
# A test to see if a deterministic fetchgit with leaveDotGit is possible.
# Short answer; yes.
#
# Q: Can .git/index be deterministic?
# A: No, impossible (it contains inode numbers). If you *must* have it, remove
# it before calculating checksums, then re-create it from the repo contents.
