Thanks for making Docker :)

Prior to the creation of Docker, did you have experience with other containerization technologies like Solaris Zones and FreeBSD Jails?

Did you at some point, either prior to or after making Docker for Linux, consider building something like Docker on top of FreeBSD Jails?

As a user of both Linux and FreeBSD, running Docker containers and Jails on each of them respectively, it would be interesting to see what FreeBSD Jails could be with something like Docker built on top of it while also taking advantage of other features on FreeBSD like fully using ZFS snapshots, ZFS send/recv, ZFS clone, vnet, and so on. Such that spinning up a container would under the hood receive ZFS snapshots from the “Docker registry” equivalent server, and it might clone the snapshot locally before starting up a container instance so that multiple container instances would be using the same locally available ZFS snapshot that was received once from the “Docker registry” equivalent.
