#! /bin/bash

# A simple script that can be used to see if an environment was built
# successfully. Note that passing these test doesn't guarantee the environment
# will work, but failing them means it certainly won't. Note that this script
# may need to be executed with sudo if the current user doesn't have chroot
# permissions
#
# This program always exits with an error code of 2 so that it can be
# distinguished from a sudo error (with an exit code of 1)
