[Libguestfs] guestmount issues with --live, but guestfish works just fine

[Adam Miller]

Hello all,
    I am having an issue with guestmount in respect to live instances
and I was hoping someone might have an idea where I've gone wrong. The
following output is from my shell session, if there's any more
information needed please let me know and I'll happily provide it.
