fsck

I have a headless Ubuntu 12.04 server in a datacenter 1500 miles away. Twice now on reboot the system decided it had to fsck. Unfortunately Ubuntu ran fsck in interactive mode, so I had to ask someone at my datacenter to go over, plug in a console, and press the Y key. How do I set it up so that fsck runs in non-interactive mode at boot time with the -y or -p (aka -a) flag?

If I understand Ubuntu's boot process correctly, init invokes mountall which in turn invokes fsck. However I don't see any way to configure how fsck is invoked. Is this possible?

(To head off one suggestion; I'm aware I can use tune2fs -i 0 -c 0 to prevent periodic fscks. That may help a little but I need the system to try to come back up even if it had a real reason to fsck, say after a power failure.)

In response to followup questions, here's the pertinent details of my /etc/fstab. I don't believe I've edited this at all from what Ubuntu put there.
