I want to install CentOS 8 on some older Dells that have storage controllers dropped by RHEL 8. The CentOS 8 kernel-plus package supports them, so I wrote a script that rebuilds the boot ISO to boot and install using the kernel-plus package from the CentOSplus repo.

I know you can use driver disks to load additional modules from elsewhere, but I wanted to end up with the kernel-plus anyway, so why not just do it during install?

Lightly tested, but seems to work. Posting here in case it is useful to others.
