Oh, I know it isn't simple.

Yes, it should (though actually making that work requires a reasonable
amount of effort, alongside which moving the entropy file to some other
place would be a minor distraction). There are plenty of other hard cases
that are even more difficult to handle, and which are easier to set up
than a read-only root.
How does all of this work when booting from other than a local disc
using NetBSD's boot code? That is, for people who boot using dosboot,
or boot from a CD, or over the network? (Or horror of horrors, use
grub or something like that.)
Is loading the entropy file really required? Or is it just a slight
improvement over what happens if it is skipped?
If it is the latter, perhaps the only real fix required here would be
to remove that WARNING printf (make it a debug printf or something).
