Here's the info I got about detecting if FAI is run inside a docker
container:

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 ?
