I was experimenting with a workflow and needed to allow a jail to mount an ISO image. This fails because the cd9660 file system does not set VFCF_JAIL:
                      can be mounted from within a jail if allow.mount and
                      allow.mount.<vfc_name> jail parameters are set
Is there a reason jails should not be allowed to mount an ISO or is it because no one has added the support?
