[Fedora-livecd-list] Modifying ISO to include per-user files

[Todd N]

Can someone point me in the direction of more extensive documentation on the -base_on option?  So far I haven't found much more than what's on the livecd-tools man page:  "Add packages to an existing live CD iso9660 image."  How do I use this option?  Does this work only for packages, or can I simply replace files as well?  Do I need a kickstart file?  Any pointers are appreciated.
 
Thanks,
Todd

You'll have to run mkisofs with the appropriate options for making the
CD bootable on your arch.   On x86, that's something like 'mkisofs -b
isolinux/isolinux.bin -c isolinux/isolinux.cat -no-emul-boot
-boot-info-table -boot-load-size 4 ....'

Alternately, you can also use the --base-on support to build derivative
images
