# set, but we have to do something with the reservation_name since we
    # need to be able to reuse the reservation name in a new one. We cannot
    # clear it, since a NULL reservation_name means it was reserved via the
    # web interface and not allowed to be messed with by the pre-reservation
    # code. Look at Node::CheckPreReserve() to see what I mean. So instead,
    # we set it to something not likely to be an actual reservation name.

Another solution might be to actually set the reservation_name to the name
of the administrator when using the web interface. That would provide some
extra info, and remove this odd corner case above.
