init and init scripts

ive just been experimenting with trying to understand how init scripts 
work. .. so i wrote some from scratch.

Now i thought that the scripts would have to work out what the previous 
runlevel was (using an exported shell variable) and stop the previous 
runlevel, but this doesnt seem to be working.  It struck me that the 
shell the init script runs in when entering a runlevel wont be the same 
shell the init script for the other runlevel runs in so exported 
variable wont work, make sense ?

Could someone clarify how the current lfs init scripts detect the 
previous runlevel.

cheers

Dave
