# ``tatu_stack.sh`` is meant to run after devstack's stack.sh and stacks only Tatu.
# - it must be run from the openstack-dev/devstack directory as the stack user.

# OpenStack is designed to be run as a non-root user; Horizon will fail to run
# as **root** since Apache will not serve content from **root** user).
# ``stack.sh`` must not be run as **root**.  It aborts and suggests one course of
# action to create a suitable user account.
