If I read this correctly, this implements FreeBSD native binaries in  
the container. Did you experiment with a linux distribution inside  
instead of FreeBSD? When the linux kernel module is loaded (or build  
into the kernel), having a pure linux userland in a jail should work  
too (I never tried it, but in case of issues I would like to see the  
error messages, as I don't see a reason why this shouldn't work  
(except the userland needs a syscall which is not implemented, but  
Cent OS 6/7 should work as we use it for linux_base ports)).

Bye,
Alexander.
