* Misc changes; add missing ds.h
+ * src/resources/default*.sl: Make clusvcadm -r go to a different
+ node. Don't notice() that we're starting a service if it's
+ disabled.
+ * src/daemons/groups.c: Make clustat not interfere with startup
+ when central processing is enabled
+ * src/daemons/slang_event.c: Make clusvcadm correctly report
+ service owner after relocate/restart/enable requests.

* Commit RIND / S-Lang script engine [untested]
