+  * /etc/rc.common: New framework for service initialization scripts.
+    - Service scripts can have significantly less boilerplate logic and
+      be much simpler.
+    - Services can be enabled and disabled by the user and the system.
+    - A /etc/rc.policy file can be used to disable all service
+      initialization and manipulation.
+  * Convert service scripts to use the new framework.
+  * Clean up stderr during services initialization.
+  * Make most of the /etc/rc.d/ links at install time using the new
+    "enable" action.
+  * Stop and start services in maintainer scripts.
+  * Fix interface names in /etc/network/interfaces.
+  * Make certain service scripts create and use PID files.
+  * Buffer early service initialization output until syslogd is running.
+  * Make some service scripts a little more robust.
+  * /etc/init.d/rc.local: New service initialization script.
+
+ -- "P. J. McDermott" <pj@pehjota.net>  Mon, 02 Jun 2014 19:58:21 -0400

 busybox (1.21.1-4) trunk
 
   * /etc/init.d/httpd: Add missing space in start message.
