+The option "udev_db" does no longer exist. All udev state will be in
+/$udev_root/.udev/ now, there is no longer an option to set this
to anything else.
+If the init script or something else used this value, just depend on

+Default location for rule sripts and helper programs is now: /lib/udev/.
+Everything that is not useful on the commandline should go into this
+directory. Some of the helpers in the extras folder are installed there
+now. The rules need to be changed, to find the helpers there.
+
+Also /lib/udev/devices is recommended as a directory where packages or
+the user can place real device nodes, which get copied over to /dev at
+every boot. This should replace the various solutions with custom config
+files.

+Udevsend does no longer start the udev daemon. This must be done with
+the init script that prepares /dev on tmpfs and creates the initial nodes,
+before starting the daemon.
