Comment 18 for bug 1015531

Meant to comment on the os.sep thing - since the existing code already uses '/':

  absolute_path = os.path.join(fs, path.lstrip('/'))

and we don't support compute nodes on any platforms where '/' isn't the path separator, I don't think it's an issue.

No problem with a later general "switch to os.sep" cleanup in Nova, though.
