I've been looking, but I haven't found it.
If I do find it, will it answer the question?

Whatever is doing it, what is being done?
Is the same partition really on four different mount points?
To me, the above looks rather scary,
rather like my first encounter with LVM.
It was in the middle of an install.

To me, the most important thing that should be in release
notes is what will break from an extant release.
The next is what will look different enough to be scary.
I'm not sure which this falls under.
