Init.c, making it chroot

[Erik Udo]

How can i make init chroot after executing /etc/rc, and executing 
/etc/rc again in the chrooted enviroment?

For this to work, i'd like to know at what point do i call chroot(), 
becouse init.c uses fork() at the point where it runs the rc script.

The thing is, i want to run a whole system in a chrooted enviroment in 
this livecd i'm making. But the command "chroot /mnt/root /etc/rc" 
returns after the /etc/rc has been run, dropping me back from the 
chrooted enviroment. And if it doesn't, init never starts the multiuser 
mode.

So how can i go to the multiuser mode in a chrooted enviroment? I guess 
the only way to do that is to modify init.c

Any help/feedback is appreciated.

Cheers, Erik
