Comment 4 for bug 239674

I don't agree with that rationale of marking it won't fix.

Regardless of whether FAI has a documented workaround for this bug, this is a bug in Ubuntu's grub package, where a normal user interaction with the grub configuration file leads to extremely strange results and an unbootable system. There are other ways to encounter this situation besides FAI, such as any configuration management system that wants to update the general initial settings in the menu.lst file.
