  | though that would be secondary if there were support to configure a dump
  | device after boot.  FreeBSD has had a dumpon(8) utility since 2.0.5.

Of course NetBSD can do that, see swapctl(8) -D  and more commonly, the "dp"
flag (like "sw" for swap, either one, or both, can be used in a "swap" type
entry) in fstab.

The only conceivable reason I can imagine for wanting to pass dumpdev
via the boot loader would be if the kernel were crashing before getting
init started (no chance to process fstab at all).
