 you're going to crash your system.  Given this info, the goal should always be
 to write "oneshot" services that have RemainAfterExit set to yes.
 
+## Target and Service Dependency Details
+There are some tools available out there to visualize systemd service and
+target dependencies (systemd-analyze) but due to the complexity of our design,
+they do not generate anything very useful.
+
+For now, document the current dependencies on a witherspoon system for
+reference.

+R = Requires
+W = Wants
+A = After
+B = Before
+S = Start (runs a command to start another target or service)
+(S) = Synchronization Target
