Probably, but as I mentioned in the commit message that Pythonic
exceptions are completely over engineered that no-one can get them. I
think you missed the fact that the exception can happen at any time
when FS is mounted and when it's not mounted yet. I suggest you think
more of this code... (Yet it admits that I may have made mistake
myself, see above)
