      .ARM-based systems fail to update with a 64k page size kernel when `vdo` is installed

      While installing the `vdo` package, RHEL installs the `kmod-kvdo` package and a kernel with `4k` page size as dependencies. As a consequence, updates from RHEL 9.3 to 9.x fail because `kmod-kvdo` conflicts with the 64k kernel. To work around this issue, remove the `vdo` package and its dependencies prior to attempting to update.

      Description of problem:
      When testing installation on aarch64 with kernel-64k selected in anaconda (bug 2164819), it was discovered that the regular 4k kernel-core gets installed as well.
      This is caused by the vdo package, which depends on kmod-kvdo, which depends on kernel-core.
      As a result, both kernel-core and kernel-64k-core get installed and the default kernel selected to boot is kernel-core, not the selected kernel-64k.

      The problem doesn't happen when installing the Minimal package set, which doesn't install the vdo package.

      Version-Release number of selected component (if applicable):
      anaconda-34.25.3.5-1.el9 + commit from https://github.com/rhinstaller/anaconda/pull/4869

      How reproducible:
      Always on aarch64

      Steps to Reproduce:
      1. Run installation, select the "Server" environment to be installed. Also select the kernel-64k to be installed (this option is also available on the software spoke).
      2. Finish the installation and check the installed kernel packages.

      OR

      Install the vdo package on a system with only kernel-64k installed.

      Actual results:

      • kernel-core and kernel-64k-core installed
      • kernel-core is the default kernel to boot

      Expected results:
      Just kernel-64k-core installed.
