Attempting to PXE boot from the BaseOS/x86_64/kickstart/images/pxeboot/ files results in repeating messages
Invalid or corrupt kernel image
eventually changing to
Could not find kernel image: centos8.2.x86_64/vmlinuz
I downloaded the files again, from a different mirror, and they are all the same. Wiped the files and recreated /tftpboot/linux-install/centos8.2.x86_64/. No dice.
