It seems a little inelegant to have this proliferation of pesudo-fs type allowances, but it's the direction we've gone. In the meantime, you could pre-mount the child jails' fdescfs when the parent jails are created. That's pretty messy, especially considering it means you have to first pre-mount their devfs as well. But it's likely all the permissions will allow. - Jamie
