What file resets fstab on persistent live environments?

I'm trying to add lines to my /etc/fstab file.
but the lines I add get cleared on reboot because I am using a persistent live USB stick.

I don't want a lecture. I just want to know which file writes the /etc/fstab file at restart and I want to alter that file so that I can auto mount the disk I want.

So this is not really a question but more like a request.

I am requesting the location of the file/files that are responsible for writing to or resetting /etc/fstab on restart.

For my LiveUSB install with Ubuntu 11.10 (which has a casper-rw persistence loopback file), the file that worked for me to have drives mounted automatically is:

/usr/share/initramfs-tools/scripts/casper-bottom/12fstab

I added lines into that script which worked to add new drive mounts upon boot-up. The odd thing is that my /etc/fstab file does NOT reflect the drive mounts. This would seem to suggest that the /etc/fstab file is just a dummy file or something to the LiveCD setups. Not sure, but changes added to the 12fstab file DO persist.
