docker 1.8+ no longer needs dind

[jessfraz]

ping @tianon idk what to make the entrypoint tbh or if you think this is too soon ;)

[jessfraz]

hmm weird errors... need to investigate why...

[jessfraz]

the windows side is because i need to update those servers

Is this still needed? https://github.com/docker/docker/blob/master/hack/dind#L14

Ohh, because it auto-mounts the cgroup hierarchy? Very interesting indeed.

IMO we should still keep the entrypoint around for a while since it'll still be needed on older Docker versions, but making it do the mounting nonsense conditionally based on whether we've already got it all mounted seems really sane. 👍 (ie, if ! mountpoint -q /sys/fs/cgroup; then ...)
