There are at least three scenarios where grub2 can hang waiting for a
keystroke prior to booting. This is obviously fatal on a machine without a
keyboard. At least as grub2 is configured on Ubuntu:
1) On Ubuntu/Debian systems "apt-get upgrade" can trigger "grub-setup". If by
chance there happens to be a USB drive attached with Linux on it... grub will
find it. And suddenly you have two OS's in grub.conf and grub changes behavior
2) If a previous boot fails (for example because of a power failure in the
middle), the next boot waits forever for a keypress. /etc/grub.d/00_header
explicitly does this, so the behavior was intentional.
3) On a kiosk, if a visitor happens to press the shift key (or it is stuck) at
boot time, the machine won't finish the boot.
While this behavior is more or less documented at:
https://help.ubuntu.com/community/Grub2#Boot Display Behavior
It is not good behavior for kiosk and remote machines.
This bug report is to suggest that grub be altered so there is NO REASONABLE
WAY to configure grub to wait forever. That all paths through grub2 should
eventually boot something, even if the
timeout is long.
Screens showing grub2 on a public kiosk:
Are not good advertisements for Linux :-)

That's grub 1.97 there on the lower screen.
