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, -- Ken. brownfld@irridia.com
