serial console config package?

[Jiann-Ming Su]

I've been installing CentOS via PXE and using a serial console
interface.  The installation works great.  I notice that during the
install process, the following line gets added automatically to
/etc/inittab:

  co:2345:respawn:/sbin/agetty ttyS0 9600 vt100-nav

Which package does this?  Is it kudzu?  Thanks for any insights.
