I played with this a while back and found that you are severely limited
for the name length.  Using the container name for that is, sooner or
later, going to overflow that limit and possibly generated an error on
container startup.  I think it's a kernel limit and not configurable or
negotiable, but that was a couple of years ago and may have changed.

YMMV
