While a cool hack, please don't do this in production.

Its perfectly fine to import physical servers into virtual machine images, but it completely defeats the purpose to dockerize whole servers.

Obviously this isn't a great way to use docker, but wow is it neat. I could see this potentially be used to make a copy of a running legacy server as a temporary solution or as an emergency backup.

Ah, there's a tool that does this in general, neat: http://devstructure.com/blueprint/

Convert Servers to Services. Convert Services to Containers

This is completely missing the point of containerisation.

If you're dumping a server or a large bunch of applications inside a container you're doing it wrong.

I can't believe the number of people I've seen running practically whole operating systems inside a container.
