# Create a user account suitable for running DevStack
# - create a group named $STACK_USER if it does not exist
# - create a user named $STACK_USER if it does not exist
#
# - home is $DEST
#
# - configure sudo for $STACK_USER
# ``stack.sh`` was never intended to run as root. It had a hack to do what is
# now in this script and re-launch itself, but that hack was less than perfect
# and it was time for this nonsense to stop. Run this script as root to create
# the user and configure sudo.
