Yes, in fact we do have entropy generators in some cases, especially on
Solaris. I think this is a very good idea -- it would be extremely nice
to see this especially since SO much more is dependent upon entropy
these days. More than about 7 years ago I would have thought entropy
was a nethack clone.

Of course, in my case deleting the /dev/random character node still
doesn't allow entropy to drain in (after at least a month) so I suspect
the kernel's entropy generation would be sufficient if it didn't
artificially stall or drain from within the kernel.

Thanks much,
