I’m more of an LXC kind of guy, but I get the switch. I don’t do much docker these days, outside of a few work scenarios outside of my control.

Personally I don’t like RH under IBM, so I won’t go with fedora either. Fantastic community, bad business behind it (a story as old as time).

Its one of the reasons I appreciate Debian as much as I do, and contribute with Sid as often as I can, mostly using sid as a mirror of what I’m doing on my Deb stable boxes and finding breaks.
