This is just a heads-up because you are likely to run into this at some point.
The recent errata kernels use dynamically linked CONFIG_SCSI and
CONFIG_BLK_DEV_SD. The anaconda mk-images.ia64 script doesn't handle the latter
being a module, so SCSI disks can't be accessed during install when a recent
kernel image is used.

Yep, this is already done in rawhide anaconda
