 You can easily script that. Boot into a script that generates
a proper /etc/inittab then executes into "busybox init". Adding
specific code to busybox for this only amounts to bloating it.

 systemd is a wonderful example of how not to design an init process.
The myth of the all-purpose "init" binary really needs to die: see
 http://www.skarnet.org/software/s6/s6-svscan-1.html

 Process 1 can be a script that does things - like getting the value of
/sys/class/tty/console/active - then executes into the "stage 2", i.e.
long-running, init binary of your choice. Adding more stuff to the
init binary instead of using a script is going the way of systemd and
Upstart, which I would very much like busybox to avoid.
