IOW what would people use it for. For example one goal to be able to use the off-the-shelf images available on docker.io (or other linux images) with docker and/or kubernetes so as to be able to migrate application stacks to a FreeBSD base. There's a *lot* of work to be done to achieve this mostly in the Linux emulation layer. I rather suspect that this is what most people expect of docker and I can certainly see how it could be used in real world applications and make FreeBSD an alternative to Linux as a host OS. Another goal is to be able to create layered FreeBSD based container images from Dockerfiles and share (publicly or with a limited group) them in the same way as Linux container layers are then that should be rather less work - and ocijail seems to be a starting point. Is this something people want to do ? Does Docker provide any benefits over Nomad/iocage/cbsd for this use ? Is there enough interest to create a critical mass of images ? -- Steve O'Hara-Smith Odds and Ends at http://www.sohara.org/
