I think that the default boot behaviour will not need *any* shell
commands, because we can implement this easily in C function calls.

It is just when a user wants to redefine boot behaviour that the shell
interface comes into play, and then it's the user's decision if he has
simple needs that can be implemented with the old parser, or if he
needs more scripting capabilities and has to enable hush.

Best regards,
