Uh, `what do you think you'd do?' You'd put the device corresponding
to the swap partition in /etc/fstab.
Actually, since there's no default swap partition any more, the
`NetBSD swap' type isn't needed. Perhaps I should have said `NetBSD
dump' -- although I think we should probably switch to configuring the
dump partition explicitly.
