Bug#422851: grub-pc: Configuration fails if there is no /dev/fd0

Wed May 9 09:15:04 UTC 2007

It seems that my particular failure is caused by my /boot being on RAID
and so is unrelated to this exact bug:

Backtrace:

                path = <value optimized out>

Line 129 of grub-probe.c is not main() however, it's probe (), so I'm
not sure how to debug this further. Shall I file a separate bug?
