Comment # 15 on bug 907457 from Michael Chang

On pc-bios platform, perl bootloader historically uses hd0 grub device provided
by device.map as the MBR device to install. The device.map was created by YaST
during installation time, iirc. So this can be yast related ??

The issue here can be fixed if by-id names is used in device.map. I vaguely
remember in openSUSE it should had been using by-id name in device.map, but I'm
not really sure and I'll check it.

And how to correct such errors via maintenance update ? User has to correct the
device.map manually to reflect their (setup) changes anyway, so in this regard
it looks like "won't fix" or invalid.
