What does init'ing /dev/random entail? The silly user in me just
expects something as /dev/random to magically work ;-)

Please don't rule out that fact that I may have done something
unbelievably stupid when configuring the machine - I'm relatively new
to NetBSD (although a long time Linux user).

An update:

I've upgraded the machine to NetBSD-2.1, with up-to-date sources as of
a few hours ago, in order to generally update the machine, but also to
get the fixed init(8) to allow me to mount an MFS /dev.

Still no joy on the /dev/random front:


  root@sparc:~> dd if=/dev/random bs=8 count=8
  dd: /dev/random: Device not configured

But the symbols (and my kernel config file) say pseudo-device rnd is
there:

  root@sparc:~> nm /dev/ksyms | grep rnd_cdevsw
  f0221300 A rnd_cdevsw


I've compiled a fresh kernel with RND_VERBOSE defined in
sys/dev/rnd.c, a chunk of boot messages follow (missing sections shown
as ...). Note the low entropy messages and the messages from named (BIND 9.3.1):
