Bug#462701: 462701: grub: savedefault menu.lst option results in unbootable system

[Raj Kiran Grandhi]

I have experienced this problem with grub failing to load after an 
unclean shutdown. It happened on a cluster running debian etch. Whenever 
there is a power outage, *some* nodes fail to boot. Connecting to their 
console shows that they hang when loading grub.

I had got around the issue by just bypassing grub altogether and 
pxe-booting the nodes from the server. Before that, either a 
grub-install, or a journal recovery seemed to fix the system till the 
next unclean mount.
