Nah, some of my older bug reports would be eligible to drive in some
countries. :-)

You're thinking of the wrong bug. #588675 is the bug # for /proc/mounts
having "/dev/root" listed as the device for the root filesystem. Your
previous mention indicated you would expect "/dev/sda6" to be there. I'm
guessing prior to wheezy, when you were using BLK_DEV_IDE_PMAC, you would
have been seeing "/dev/hda6" listed as the root device?
