Quoting "Plant, Dean" dean.plant@roke.co.uk:

I am trying to use kickstart for automated builds from a DVD. Some of the machines have DVD's drives and some have CDRom drives only. With the CDRom only machines I would like to plug in an external DVD drive via USB and use this to kickstart.

The DVD only machines work correctly with a isolinux.cfg as

label test kernel vmlinuz append initrd=initrd.img ramdisk_size=8192 ks=cdrom:/test-ks.cfg

Machines with a internal CDRom drive and the external USB DVD do not find the kickstart so I figure that I need to change the ks=cdrom:/test-ks.cfg to something else.

I have tried the following with no success

label test2 kernel vmlinuz append initrd=initrd.img ramdisk_size=8192 ks=cdrom1:/test-ks.cfg

To save me producing lots of coasters can anyone tell me what the "ks=cdrom" should be changed to.

Boot into rescue from USB DVD drive, and see what device it gets assigned. For example, my DVD drive appears as /dev/scd0. So in my case, something like "ks=hd:scd0:/test-ks.cfg" to work (haven't tested it). Note that depending on actuall hardware configuration, your external DVD drive might appear under different names on different machines (for example /dev/scd0 on one machine, and /dev/scd1 on another machine).

To avoid coasters, use DVD-RW, DVD+RW or DVD-RAM when experimenting...
