[CentOS] mingetty on centos 6

hi all,

on centos 5 - I could trim the number of mingetty's running by editing 
/etc/inittab

on centos 6 there are none in the /etc/inittab file but it reverences 
/etc/init/tty.conf.
I dont see in there how to control how many mingetty's get started.
Where is that?

THanks,

Jerry
