I'm putting together a disk that'll be used to upgrade systems to CentOS 5.3. Some of these systems have accessible internal DVD drives and others don't. My kickstart file is quite simple and I bury it inside the initrd so that I don't have to specify a device on the boot line. This has worked for me with CentOS 4.4 disks in the past. The goal for the install/upgrade is for it to be done largely unattended. The install method is cdrom.
This setup works quite well when booting from the internal drive. But on systems where I can't use that drive and I use an external USB connected DVD drive instead, I end up at this prompt that says "The CentOS CD was not found in any of your CDROM drives. Please insert the CentOS CD and press OK to retry". Of course, the disk is present and it's the one the system has booted off of and where it's found the initrd and kickstart. It also has a correct discinfo file.
Quite interestingly, if I select the back option a few times, it appears to select the correct drive and boot. Here's what I see on Alt-F3.
Many repetitions of:
11:04:10 INFO : starting to STEP_URL
11:04:10 INFO : trying to mount CD device hda
11:04:10 INFO : ejecting /tmp/cdrom...
11:04:11 DEBUG : going to set language to en_US.UTF-8
11:04:11 INFO : setting language to en_US.UTF-8
11:04:11 INFO : starting to STEP_URL
11:04:11 INFO : trying to mount CD device hda
And then it succeeds:
11:04:11 INFO : trying to mount CD device scd0
Questions:
- can I force it to look at scd0 for the CentOS distribution?
- even better, can I have it try both, so that I can maintain a single kickstart and isolinux entry?
Many thanks,
Hardik.
