That can't work as non-root user unless docker install is b0rk3d as you
say. On both hosts `docker info` works as root and doesn't as condor:

Centos 6 shell:

Centos 7 shell:

Centos 7 StarterLog:

Another difference is that docker version is 1.7 on centos 6 (last
available) and 1.13 on 7.

Personally I think kool-aid and long time is a bit of a mixed metaphor,
but then again: confusion is one of the main side-effects of
antihistamines so whaddya expect. ;)
