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
