The only environmental variable set during %post is $ANA_INSTALL_PATH
which points to the installroot (usually /mnt/sysimage). It can be used
in a %post --nochroot to copy things from the installer root to the
target's root filesystem.
This removes the %post --nochroot section because the image is not
accessable at this point in the process. Items that need to go into the
/ of the iso need to be added in the final iso creation templates, like
x86_64.tmpl

This includes packages that anaconda runs from the installed system
during installation. It includes grub2, grub2-efi, shim, efibootmgr
among others.

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
