Is there a specific reason why you chose to use "select NON_ROOT"
instead of "depends on NON_ROOT" for all these options?
As configuring NON_ROOT=n is quite a drastic decision, I don't
think you should let that be revertable such easily by all those selects.

Ah, finally a few "depends on".

I think it would be clearer to use positive instead of negative logic.
What about calling the option "MULTIUSER" instead of "NON_ROOT"?
