-It is also possible to leave the existing init in place without renaming it; in
-this case you would rename the new init to something else, such as init-ng.
-Then, on your kernel boot command line, you would add "init=/sbin/init-ng"
-(without the quotes) to have the kernel use it instead of your current init.
+Once you have rebooted successfully and logged in as root, typing 'init' (or
+'init-ng', if you installed the second way) on the command line will display
+the commands that init-ng understands.
