Where do those "'"s come from???

I also have those "'" on one (out of 3) md's. Maybe it's debian
specific? Or only debian etch specific? Or only debian /dev/md0
specific.... It's only on /dev/md0, like this:

backup:~# mdadm -D /dev/md0

       6       8       17        4      active sync   /dev/sdb1

What exactly is listed in mdadm.conf for /dev/md0??

nothing.
