runlevel 2 vs 3 vs 5 deprecated in sarge?

[Joao Clemente <jpcl@rnl.ist.utl.pt>]

I was testing some stuff that needed rebooting my sarge installation an 
I tought to myself that it was a waste of time to startup X at every 
boot....
So I headed to /etc/inittab to change it to runlevel 3... but I was 
amazed to see that the value there was 2 !!!!

So, do those standarts of 5 = multiuser + X, 3 = multiuser - X, ... 
stoped being used in sarge? Why?

I'm using sarge intalled with rc2 business-card installer
