I'm not sure if there's any milestone set for that, but as I see it, is quite far, as I've been more than one year in the project, and we haven't got out of redhat based distributions, I see really hard to support non-gnu oses but if that's what was decided, let's go for it.

but will be running the infra and jenkins scripts/jobs on such target 
slaves. why not keep it to a single standard?
