Yeah that's true. Should always try to mirror prod as close as practical in dev, and OSX != Linux. So I use just one Ubuntu lts VM with docker backed by zfs.

Yeah that's true. Should always try to mirror prod as close as practical in dev, and OSX != Linux. So I use just one Ubuntu lts VM with docker backed by zfs. That way, I can ssh to it and predictably recreate any number of isolated environments. Way faster than vagrant and still provides isolation, although docker could be driven by it. There's always a need for some sort of deploy/configuration mgmt to bootstrap to speed up testing and reduce tiny difference gotchas. The other good things are that it doesn't sacrifice osx usability, no reboot is needed and it doesn't require repartitioning.
