"mount changed" message
I noticed a message in a few SuperDuper logs recently. It says "mount changed" for a disk, but as you can see below from the log excerpts I have included, neither the source nor target disks were the disk whose mount change was being reported. Any idea what the meaning of this might be? The clone seems to have completed successfully.

P.S. After checking a bit more, it seems that disk0s3 is the recovery disk partition (hidden). I suspect that this message does not involve SuperDuper, but it did get reported through SuperDuper's log, and I've never seen that message anywhere else. Maybe every so often the recovery partition gets quickly mounted and then unmounted as some kind of check by the operating system?

We log all drive mount operations in case they *are* relevant. They're not errors.
