Section Number and Name:
Chapter 2.3, step 3:

The given rsync command will copy the Pulp data to /var/lib/pulp/pulp which is wrong.

Chapter 2.4.2, step 4:

I would suggest to also --enable=rhel-8-for-x86_64-baseos-rpms

Chapter 2.4.2, step 6:

I had to start over this step several times because of filesystem sizing. I don't know if there are some hints for this anywere - at least I missed them.

Chapter 2.4.2, step 9:

This step does not work because the option --enable-foreman-proxy-plugin-remote-execution-script is unknown in version 6.11. After the upgrade to 6.12 it works.

Chapter 2.4.2, step 17:

It is not sufficient to copy the files in /etc/virt-who.d/. virt-who will not start because the file /var/lib/virt-who/key is missing. I had to create new password hashs with virt-who-password. May be restoring /var/lib/virt-who/key would have worked also.
