I can take a Clonezilla-generated ISO and extract the contents, then manually edit the syslinux.cfg (and other .cfg's) to adjust the boot parameters after creating the ISO, then repackaging it up. However, I'd like to be able to have these boot parameters be changed while creating the images instead of having to throw in several extra steps (that I don't want the customer doing in the first place). Ideally this can be done by modifying the source Clonezilla image so that it would automatically append to the default boot parameters.
I had hoped that Clonezilla would take it's own modified boot parameters (via cfg files, not manually typed in) and simply carry them forward to the child ISOs, but alas, it does not.
Edit: Bonus points for also changing the .png file that it uses for the background. It doesn't carry that over from parent to child either.
