Answer the following question:

A challenge for the SibylFS authors is that there exists no reference implementation of POSIX, but there are many file systems that implement something that is close to POSIX.

Give an example of such a non-determinism in the SibylFS specification and explain what degrees of freedom it provides to file-system implementors.
