I shortly tested the CROPS docker-based setup after watching some
presentation at ELCE 2016 in Berlin. It basically worked but I experienced
the filesystem slowness your are talking about. I ended up waiting hours to
see a simple core-image-minimal build complete (even after giving more
cores to docker). One more point is that slightly more complex build
scenarios, i.e. building resin.os, also required tweaking docker run
parameters for the build container in order to give bitbake access to
features like loop devices it needed (not always easily debuggable issues
indeed). Turned out I decided to stick with more canonical linux based
environments for the moment.

Anyway, the technology behind CROPS is *very* interesting to me, and I'd
like to hear from people closely involved (Tim?) what the state of the art
is and what we can expect to see in the near future. IIRC, the roadmap for
Yocto 2.3 release was supposed to resurrect the Eclipse plugin and adopt
CROPS as an alternative for running eSDK in a seamless way on different
development host OSs. Beside from the images on docker hub and the github
projects that didn't have high activity in the latest months, I hardly find
discussions and documentation on the whole approach. Isn't this hot enough
anymore or are there big issues that will prevent this technology from
taking off. I often manage SDKs for Windows-minded developers and I
strongly yearn to find a better approach to help them feel at home while
building stuff for OE/Yocto based systems...
