dumpon should perhaps issue a warning if the device looks like
something that has a filesystem on it.  It should refuse to dump to
any device that was opened by the time the dump happens.

This used to be an (undocumented) feature, but turned into a bug over
time.  A device with (minor & 07) == 1 is no longer something very
special.  Swapping could have happened to anything else, nor would it
make much sense that you could dump to /dev/rfd0.1720 but not to any
other floppy device. ;-)  Let alone tape drives...

Well, i didn't say that everything is OK with the current behaviour
either: it's only that i don't think we should restrict it to swap
partions only.

Never trust an operating system you don't have sources for. ;-)
