Live system's /etc/inittab

["Wakefield, Thad M." <twakefield@stcloudstate.edu>]

How is live system's /etc/inittab created? The file is different than chroot/etc/inittab. Actually it is different than any inittab file on my computer.

Specifically, all inittab files on my computer have:
   T0:23:respawn:/sbin/getty -L ttyS0 9600 vt100
The file on the live system has:
    T0:23:respawn:/bin/login -f user </dev/tty >/dev/tty

Thanks
