Hmmmm .... It's not so clear to me, but that might be a deficiency @ my 
end :-/. I would like to run 64-bit binaries compiled on/for linux boxen 
(specifically CentOS/RHEL 6) on my FreeBSD boxen, currently 3 in number, 
all various AMD64 CPUs, all running 9.3R. My question only involved 
docker to the extent that the docker wiki page alludes to apparently 
newly available (as of last summer) 64-bit linux binary support, which 
is what I am really interested in.

I *AM* (separately) interested in docker, for various reasons. 
Specifically, I would want to use it as a lightweight VM system, which I 
*think* works under Linux. I.e. you can run a container of a non-native 
OS if it is CPU compatible w/ the host CPU. As I understand things, that 
is not feasible w/ jails, although I have found some URL's which claim 
otherwise. Clarification on that point would be welcome as well. I have 
asked before & been told it was *NOT* feasible, but maybe things have 
changed or I am missing something. TIA & have a good one.
