Hi Michael, I am currently using virtualenv and pip manually to "deploy" lava-server and lava-dashboard on my computer, so I can work on the Graphics dashboard extension. I am not using l-d-t as it brings in too many dependencies (databases etc) which I don't need (nor want) running on my development box. Will the change to zc.buildout affect this use case? Thanks, Alexandros _______________________________________________ linaro-validation mailing list [email protected] http://lists.linaro.org/mailman/listinfo/linaro-validation
