Huh?  That's not correct.  You can still introduce entropy into the
random pool by writing to /dev/urandom or /dev/random.  It is true
that there has been some changes to the design of /dev/random, but I
assure you as the original /dev/random developer, was consulted and
involved in the design discussions.

Anyway, this is off-topic for TUHS, but if you have specific
questions/complaints, feel free to address them to me and Jason.  Your
comments do make me suspect that there are some fundamental
misunderstandings at work.
