Ubuntu's reseed(8) can be used to seed the PRNG state of a host. The script is run when the package installed, and anytime su executes the script.
reseed(8) performs a unsecured HTTP request to random.org for its bits, despite random.org offering HTTPS services. The Ubuntu Security Team took no interest when contacted by email (no reply); the point of contact listed in the man pages took no interest when contacted by email (no reply); and a launcher bug report was not acted upon (https://bugs.launchpad.net/ubuntu/+source/reseed/+bug/804594).
