Does the kernel _really_ do a coredump dump on a b partition,
regardless of the partition type in the disklabel?
Since swap is now optional, reserving b partitions for swap is
presumably optional. Therefore reserving B partitions for _dumps_
(which is, historically, just a side-effect of them being swap
devices) should be optional too.
I think it'd be safer and more correct to only do wildcarded dumps
onto B partitions that are labelled as type `swap'.

might dump on a B partition that's in use as a filesystem, and that
would be a bug.
