Subject2.6 early userspace init

Hi folks,

how about adding something like this to init/do_mounts.c?

I wont to be able to fetch the boot= parameter via /proc/cmdline
in kinit and choose the boot devices, so I dislike the boot=0:0
suggestion.
Also, should the above code clear the init= parameter, i.e.
main.c:execute_command?

Cheers,
Michael.
