This patch fixes the situation with i386-pc where grub-probe &
grube-setup are searching for the root fs for grub files and they
happen to be on the same file system as the root ("/") filesystem. If
this is the case if when probing /dev , if the partition is a sd* it
will not find it because it will find /dev/root first (this is a
mistake).
On Fedora and other Redhat systems /dev/root is an actual device
node (in this case my root partition is sda1):
[EMAIL PROTECTED] grub2]# ls -l /dev/root
brw------- 1 root root 8, 1 Feb 17 13:11 /dev/root
[EMAIL PROTECTED] grub2]# ls -l /dev/sda1
brw-r----- 1 root disk 8, 1 Feb 17 13:12 /dev/sda1
The problem here is once grub sees this it has no idea what /dev/root
is so it cannot properly resolve it to /dev/sda1. So the best thing to
do is if you see /dev/root to just move on until you find the device
node with the real name.
