I just happened across this article, recommending that discardable output be redirected to /dev/random instead of just thrown into /dev/null

Looks interesting - keen to hear other thoughts.
Stirring up your CSPRNG cannot hurt. Bandwidth seems to be a possible bottleneck, but if you’re just redirecting somewhat noisy scripts, it’s not going to cause a problem. On a related note, it’s well worth reading “Myths about /dev/urandom” (http://www.2uo.de/myths-about-urandom/ <http://www.2uo.de/myths-about-urandom/> ) as well as the pages it references. Linux’s use of the blocking-when-entropy-is-low /dev/random is somewhat confusing, and at times very frustrating - and for the vast majority of use cases, completely unnecessary. ( I raise this only because the quoted article above still suggests that you need to keep the “entropy pool topped off at full”, which is perpetuating the myth)
