  | No, the cprng named "kernel" is used _inside_ the kernel.

It hadn't occurred to me before that that name is significant.
When I get two messages after a boot (which looks like it might be
every time), one of them says "kernel" (seems to be the later one)
and the other (the one soonest after a boot) says "sysctl".

That is ...

I don't reboot this system all that often (it has occasionally panic'd,
haven't looked into why - but it is current, so perfection isn't expected).
and then resume it (and then deal with virtualbox not having any good way
to inform NetBSD that it has been hibernating without its knowledge for
some indefinite time).  This morning's reboot was deliberate to upgrade
virtualbox.
