Someone mentioned [1].

So I tried busybox's init. It works great, my exp. config is at [2].

///

Also it would be possible to have a startup script (/etc/rcS) like:

#!/bin/bash

echo -n "Which init do you want to use? "
read -t 5 a # bash's read has a timeout option
if [ $? -gt 0 ]
then
echo timeout, use normal init
exec /sbin/normal_init <boot args...>
else
echo Switching to init_$a
exec /sbin/init_$a <boot args...>
fi

///

Basically, nothing hinders one to choose init's on the fly, or ?
(Well yes, they need different /etc/inittab's, but that is solvable.)
