I've got a bunch of headless servers installed in random (remote) locations all running Ubuntu 11.04. Sometimes the boxes go down and never come back up, eventually someone goes out to check on them to find them sitting at a GRUB screen.
On a normal boot, the machines scream through GRUB with no issue, but it seems like there is some sort of "failsafe" built in that if the machine doesn't boot up properly, the next time the box comes up, it stops at GRUB.
I realize this is for my safety, but due to how the machines are setup, I'd prefer it didn't happen (or at least timeout after a minute or two and try to boot again). Is there anyways to disable this feature?
