If it helps, one could try ZNETBOOT. For that, you put all the statements into one file then run the EXEC. It pulls down the indicated kernel and initrd, stacks them along with boot parms into the reader, and IPLs. It will automatically create a CMSCONF file for when you have too many bytes of boot parms to fit in the deck.
The idea is to have >one< file for a particular installation image+config so you don't have to hold your jaw a certain way and stand on one foot and chant the magical incantation. -- R; <>< On 1/2/20 6:01 PM, Hamilton, Robert wrote: > I don't use kickstart.
