Comment 10 for bug 542210

I don't think that message means the arrays are overlapping, at least for useful definitions of "overlapping." It would say this if, for example, md0 and md1 had separate partitions on the same physical disks. This is the case for my configuration, where I have 5 disks each with two partitions (256M and the rest), and /dev/sd[abcde]1 is RAID-1 on md0 and /dev/sd[abcde]2 is RAID-5 on md1.

This is a perfectly cromulent (and I think common) configuration that would elicit that message from md.
