Have you ever got the 'init: timeout while...'?
 

Have you ever got this message?:

Well, that's because init isn't initialized. The kernel uses '--init' to initialize it at boot.

Init has the '--init' option that is not shown at usage as it is used normallt by the kernel. So if
you had 'init=/bin/sh' or whatever, 'init --init' wll initialize it.

Found it in the source code!
