Arvados

Applied in changeset arvados|commit:6de67b677d281b99b53ee9a25c9228523fdf7ee2.

After some research is possible to run SystemD in docker! (I know, exciting times ahead, so good to be alive, etc. etc)

docker build .
docker run --cap-add SYS_ADMIN -t --rm --name server-1 -v /sys/fs/cgroup:/sys/fs/cgroup 1be130b04bad

which I get...
