Well, I wouldn't say it's entirely impossible to get a Docker
implementation running on FreeBSD, but probably it won't work
1:1 with all imaginable software - I conclude this from the
concept of being able to run Linux applications on FreeBSD
using our Linux ABI, which works for _many_ applications, but
not for _all_ of them, especially not for those relying on
Linux kernel mechanisms that the ABI doesn't provide a proper
"translation" for. In those cases it's probably easier to use
native FreeBSD solutions: install the ported application into
a Jail. Yes, I know, Docker is much more than Jail in terms
of functionality...

Oh, that's why I see this on Mac OS X related software so often! :-)

Where the only answer is "more beer". :-)
