According to `man dumpon` (on a 5-STABLE system):
Since dumpon cannot be used during kernel initialization, the dumpdev
variable of loader(8) must be used to enable dumps for system panics
which occur during kernel initialization.
But I don't find 'dumpdev' referenced anywhere under /usr/src/sys/boot/. Is
the documentation wrong?
