Description of problem:
Automated kickstart installs of RHEL WS3 U4 on new Dell Precision 470
systems with IDE DVD burners generate incorrect symlink
/dev/cdrom --> /dev/hdc
during the install process. Manually running /usr/sbin/kudzu after
firstboot fixes the symlink to
/dev/cdrom --> /dev/scd0
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. perform a kickstarted install of RHEL WS3 U4, allowing automatic reboot
2. Wait for system to come up
3. Type `ls -l /dev/cdrom`
Actual Results: lrwxrwxrwx 1 root root 9 Jan 22
01:35 /dev/cdrom -> /dev/hdc
In this case the CDROM will work fine for burning only if ide-scsi
module is removed, cannot be mounted for reading at all.
Expected Results: lrwxrwxrwx 1 root root 9 Jan 22
01:35 /dev/cdrom -> /dev/scd0
And when this link is there and ide-scsi loaded, all works fine
(reading and writing).
The systems have 2 SATA drives that show up as sda and sdb. The IDE
DVD drive is secondary master.
Here's what kudzu's changing when I run it manually. Output of (diff

Is ide-scsi appended to the kernel commandline in grub.conf?
Yes, ide-scsi is on the grub.conf kernel commandline:

This problem is resolved in the next release of Red Hat Enterprise Linux (RHEL
4). Red Hat does not currently plan to provide a resolution for this in a Red
Hat Enterprise Linux update for currently deployed systems.
With the goal of minimizing risk of change for deployed systems, and in response
to customer and partner requirements, Red Hat takes a conservative approach when
evaluating changes for inclusion in maintenance updates for currently deployed
products. The primary objectives of update releases are to enable new hardware
platform support and to resolve critical defects.
