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

(cherry picked from commit 6f6af862c6)
We don't need biosboot partitions, and the urls should point to rawhide.
On minimal installs dracut needs to have tar and dracut-network
explicitly included.
Also adds a check for a bad url repo, and fix ram calculation for
appliance mode. Updates the README.livemedia-creator documentation.
