Comment 33 for bug 1333140

SneA, errors on the mmcblk0 device itself, and "-boot" are something different then. In general we do want to blkid those, as if they have a medium then we do want to recognize them. It wuold be intersting to see if we can detect whether they have a medium before we run blkid, perhaps there's something in /sys/block/mmcblk0/ ? Either way, new bug report would be appreciated.
