standard for bootable CD/DVD

[Dan Horák]

Hi,

after the latest changes in the compose tool (pungi) and its config we
are closer to have a full compose for ppc64le again. The installer
image is 3GB now, so no space issues any more. But the switch in the
tool producing the ISO9660 (CD/DVD) filesystem from genisoimage to
xorrisofs breaks it again [1], because the options are not fully
compatible between these tools. And because the lorax template call to
genisoimage was used to create a PowerMac compatible image, which we
don't need with ppc64le, my question is, what is the standard that a
CD/DVD image must follow to be usable/bootable on a Power system? This
should cover PowerVM LPARs, qemu/kvm guests and PowerNV/OPAL bare-metal
machines.

https://bugzilla.redhat.com/show_bug.cgi?id=1676411 is the bug report
for the recent failure and my plan is to get rid of the PowerMac bits.
