unshare causes breakage in docker

Googling around, there are a few ways.
It looks like this could be the most consistent:
grep -E ":/docker/.+$" /proc/1/cgroup
..which is looking for cgroups under a docker cgroup
It may be refined to:
grep -E ":/docker/[0-9a-f]+$" /proc/1/cgroup
..but I can't say that for sure.
What do you think, does that sound reasonable ?
