I think the question is how much should be implemented by a freebsd port 
and how much should come from the native linux/docker implementation. 
There are two extremes:

1. Linux in bhyve, docker is running completely in Linux environment

2. A docker container in a jail with no native linux kernel, docker is 
running completely in FreeBSD environment

1 is the least convenient because it requires all the hurdles related to 
setting up a bhyve host, including proper network configuration for 
containers and pre-allocating disk space. But it also requires no 
implementation in freebsd-related docker ports apart from maybe adding 
support to docker tools, like docker-machine for example

2 would be most convenient but also most difficult as all smallest 
docker features would need to be ported natively to FreeBSD

I believe docker and freebsd-docker ports were trying different 
approaches somewhere in between these extremes. Maybe the correct 
approach would be to start with 1 and make running docker in bhyve as 
convenient as possible, then slowly move to 2 as much as 
interest/resources allow?
