      .Unable to load an updated driver from the driver update disc in the installation environment

      A new version of a driver from the driver update disc might not load if the same driver from the installation initial RM disk has already been loaded. As a consequence, an updated version of the driver cannot be applied to the installation environment.

      As a workaround, use the `modprobe.blacklist=` kernel command line option together with the `inst.dd` option. For example, to ensure that an updated version of the `virtio_blk` driver from a driver update disc is loaded, use `modprobe.blacklist=virtio_blk` and then continue with the usual procedure to apply drivers from the driver update disk. As a result, the system can load an updated version of the driver and use it in the installation environment.

      Description of problem:
      It's not possible to load a new driver from driver update disk instead of an original one which is being used (in my case it was virtio_blk, used for storage access):

        [ 207.249243] e1000e: DRIVERDISK: e1000e loaded

      Version-Release number of selected component (if applicable):
      anaconda-34.25.2.6-1.el9, dracut-057-20.git20221213.el9, kernel-5.14.0-234.el9 (RHEL-9.2.0-20230115.7)

      How reproducible:
      100%

      Steps to Reproduce:
      1. Prepare a driver update disk (I just used an ISO connected to a second CD-ROM drive in a VM) containing a driver that will be in use later on (i. e. driver for a block device present in the system). Also create proper conditions so that the driver can't get reloaded – in case of virtio_blk, it's necessary to create partitioning on a virtio block device first.
      2. Start installation with 'inst.dd'.
      3. Select a driver that's already in use and continue.

      Actual results:
      The driver is not loaded in the installation environment.

      Expected results:
      The driver is loaded in the installation environment and is present in the installed system.
