[Users] How to determine a container from the filesystem?

[jjs - mainphrame]

Unfortunately that won't work if you are using only bridged networking - I
don't have any venet devices on my servers.

My host has only lo, ethx, brx, and vethnnxx devices, and the containers
have only lo and ethx devices.

The puppet "facter" program is able to figure out if if a machine is a vz
CT or a vz host, but I haven't looked into how it does it.
