Upstream GRUB doesn't do this. Your problems are caused by Ubuntu-specific patch. You have to take it to them.

This is a big issue for unattended systems. It appears the grub2 defaults, often picked up by the distributions, will wait forever for a keystroke at boot time.

---------------
We found three causes of the "headless server waits forever for someone to press a key" problem with grub2 as configured by Ubuntu:

1) "apt-get updgrade" 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 and grub asks.
2) If a previous boot fails (for example because of a power failure in the middle), the next boot waits forever for a keypress.
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.

All three issues are problems for unattended/kiosk uses of Ubunu.

------------------

An improvement here would be a grub that by default boots no matter what, but can be configured cleanly to hang instead.
