I'm not sure I mentioned this. If you are able to reproduce the
error, then after the error in "git status" the tree becomes unusable.
Not even from the local_mount. I have not found a method to fix the tree.
So what I do is:
- Before I start playing I save "cp some_tree/.git/index index.back"
- then after the error and tree damage On local mount I:
  "rm some_tree/.git/index"
  "cp index.back cp some_tree/.git/index"
  "cd some_tree; git status"

this will fix it so I can try a new iteration
