systemd uses /var/lib/systemd/random-seed to add entropy to /dev/urandom at boot time. During image creation this file is created, and if not removed everything using the image will be adding the same seed. This is only additional entropy, NOT a seed in the sense of a starting point for a PRNG, so it will be mixed with other entropy as the system runs. It isn't a good idea to use the same value everywhere so make sure it is removed in %post Resolves: rhbz#1258986
