ubuntu's grub configuration is fucked up. it was bad enough in previous
releases, and it has only got worse in Precise and Quantal.
to make it sane, you need to:
1. comment out or delete all the GRUB_HIDDEN_* shit in /etc/default/grub
and replace it with non-hidden versions. and if you want the machine
to be able boot again without manual intervention after a boot
failure, you need to disable their cretinous recordfail "feature" with
GRUB_RECORDFAIL_TIMEOUT=x (the default of -1 just makes it sit at the
grub prompt forever, which is a PITA if you don't have access to the
console)
e.g. here's /etc/default/grub from one of my ubuntu VMs:
(you probably don't need the 'console=ttyS0', that's just to make
sure I get a console.log file on the openstack compute-node).
GRUB_TERMINAL=console is useful for getting rid of any stupid boot
splash screens so you can see what's happening when the machine boots.

2. disable the brain-damaged submenu shit in /etc/grub.d/10_linux (it's
annoying, and it breaks the grub-set-default and grub-reboot commands)
