 =================
 
 Q: Can I use DevStack for production?
-    A: No. We mean it. Really. DevStack makes some implementation
-    choices that are not appropriate for production deployments. We
-    warned you!
-Q: Then why selinux in enforcing mode?
-    A: That is the default on current Fedora and RHEL releases. DevStack
-    has (rightly so) a bad reputation for its security practices; it has
-    always been meant as a development tool first and system integration
-    later. This is changing as the security issues around OpenStack's
-    use of root (for example) have been tightened and developers need to
-    be better equipped to work in these environments. ``stack.sh``'s use
-    of root is primarily to support the activities that would be handled
-    by packaging in "real" deployments. To remove additional protections
-    that will be desired/required in production would be a step
-    backward.
-Q: But selinux is disabled in RHEL!
-    A: Today it is, yes. That is a specific exception that certain
-    DevStack contributors fought strongly against. The primary reason it
-    was allowed was to support using RHEL6 as the Python 2.6 test
-    platform and that took priority time-wise. This will not be the case
-    with RHEL 7.
+
+    A: DevStack is targeted at developers and CI systems to use the
+    raw upstream code.  It makes many choices that are not appropriate
+    for production systems.
+
+    Your best choice is probably to choose a `distribution of
+    OpenStack
+    <https://www.openstack.org/marketplace/distros>`__.
+
 Q: Why a shell script, why not chef/puppet/...
     A: The script is meant to be read by humans (as well as ran by
     computers); it is the primary documentation after all. Using a
     recipe system requires everyone to agree and understand chef or
     puppet.
-Q: Why not use Crowbar?
-    A: DevStack is optimized for documentation & developers. As some of
-    us use `Crowbar <https://github.com/dellcloudedge/crowbar>`__ for
-    production deployments, we hope developers documenting how they
-    setup systems for new features supports projects like Crowbar.

 Q: Why not use packages?
     A: Unlike packages, DevStack leaves your cloud ready to develop -
     checkouts of the code and services running in screen. However, many
     people are doing the hard work of packaging and recipes for
-    production deployments. We hope this script serves as a way to

 Q: Why isn't $MY\_FAVORITE\_DISTRO supported?
     A: DevStack is meant for developers and those who want to see how
     OpenStack really works. DevStack is known to run on the
     distro/release combinations listed in ``README.md``. DevStack is
     only supported on releases other than those documented in
     ``README.md`` on a best-effort basis.
-Q: What about Fedora/RHEL/CentOS?
-    A: Fedora and CentOS/RHEL are supported via rpm dependency files and
-    specific checks in ``stack.sh``. Support will follow the pattern set
-    with the Ubuntu testing, i.e. only a single release of the distro
-    will receive regular testing, others will be handled on a
-    best-effort basis.
-Q: Are there any differences between Ubuntu and Fedora support?
-    A: Neutron is not fully supported prior to Fedora 18 due lack of

     as associative arrays. Simple compatibility patches have been accepted

 Operation and Configuration
 ===========================
 
 Q: Can DevStack handle a multi-node installation?
-    A: Indirectly, yes. You run DevStack on each node with the
-    appropriate configuration in ``local.conf``. The primary
-    considerations are turning off the services not required on the
-    secondary nodes, making sure the passwords match and setting the
-    various API URLs to the right place.
+    A: Yes, see :doc:`multinode lab guide <guides/multinode-lab>`
+
 Q: How can I document the environment that DevStack is using?
     A: DevStack includes a script (``tools/info.sh``) that gathers the
     versions of the relevant installed apt packages, pip packages and
     git repos. This is a good way to verify what Python modules are
     installed.

 Q: How do I turn off a service that is enabled by default?

     ``local.conf`` (using ``n-vol`` in this example):

 This guide will walk you through using OpenStack neutron with the ML2
 plugin and the Open vSwitch mechanism driver.
 
-Network Interface Configuration
-===============================
 
-To use neutron, it is suggested that two network interfaces be present
-in the host operating system.
+Using Neutron with a Single Interface
+=====================================
+
+In some instances, like on a developer laptop, there is only one
+network interface that is available. In this scenario, the physical
+interface is added to the Open vSwitch bridge, and the IP address of
+the laptop is migrated onto the bridge interface. That way, the
+physical interface can be used to transmit tenant network traffic,
+the OpenStack API traffic, and management traffic.
+
+
+Physical Network Setup
+----------------------
+
+In most cases where DevStack is being deployed with a single
+interface, there is a hardware router that is being used for external
+connectivity and DHCP. The developer machine is connected to this
+network and is on a shared subnet with other machines.
