It should be printed out, something like:

BusyBox v1.10.2 (Debian x-x-x-x) Built-in shell (xxx)

If that's what you get it cames out when there is a problem when booting, 
for instance, a missing kernel module for the hard disk controller, a bad 
hard disk identifier at GRUB's menu file, etc. So instead having you no 
option at all and display a black screen (because the system is halted), 
we are presented with the BusyBox.

I think that's a different thing :-?

For example, when you go fall into "init 1" you are prompted with root's 
password to get into the maintenance console or continue by pressing Ctrl
+D, so here you are indeed asked for root's password because you are 
inside the full shell and not inside the limited BusyBox environment.
