dumpdev=AUTO in rc.conf has been broken for a while from what I've
seen, despite what rc.conf(5) suggests:
dumpdev (str) Indicates the device (usually a swap partition) to
which a crash dump should be written in the event of a system
crash. If the value of this variable is ``AUTO'', the first
suitable swap device listed in /etc/fstab will be used as
dump device. Otherwise, the value of this variable is passed
as the argument to dumpon(8). To disable crash dumps, set
this variable to ``NO''.
You have to explicitly note the dump device in /boot/loader.conf and
have to reboot the box (otherwise it won't pick up the appropriate
value via kenv). Kind of lame if you ask me...
