  CHANGES WITH 233 in spe
  
 +        * DBus policy files are now installed into /usr rather than /etc. Make
 +          sure your system has dbus >= 1.9.18 running before upgrading to this
 +          version, or override the install path with --with-dbuspolicydir= .
 +
+         * The shell invoked by debug-shell.service now defaults to /bin/sh in
+           all cases. If distributions want to use a different shell for this
+           purpose (for example Fedora's /sbin/sushell) they need to specify
+           this explicitly at configure time using --with-debug-shell=.
+ 
          * The confirmation spawn prompt has been reworked to offer the
            following choices:

  Features:
  
+ * Maybe add a small tool invoked early at boot, that adds in or resizes
+   partitions automatically, to be used when the media used is actually larger
+   than the image written onto it is.
+ 
+ * change the dependency Set* objects in Unit structures to become Hashmap*, and
+   then store a bit mask who created a specific dependency: the source unit via
+   fragment configuration, the destination unit via fragment configuration, or
+   the source unit via udev rules (in case of .device units), or any combination
 -  there of. This information can then be used to flush out old udev-created
++  thereof. This information can then be used to flush out old udev-created
+   dependencies when the udev properties change, and eventually to implement a
+   "systemctl refresh" operation for reloading the configuration of individual
+   units without reloading the whole set.
+ 
  * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
    the service cgroup, which is supposed to monitor the service, and when it
    exits the service is considered failed by its monitor.
