Greetings,
FYI
The following xorriso (1.5.4) command fails on RockyLinux 9.0 and 9.1. It does not fail on RockyLinux 8.7. It fails on both macos and linux. xorriso -indev Rocky-9.1-x86_64-minimal.iso -report_system_area as_mkisofs
This is surprising since it's a very common pattern to determine how an ISO was built. Then this information is used when remastering the ISO. This technique works perfectly with debian, ubuntu, and all flavors of redhat/fedora EXCEPT rockylinux. It works perfectly with all versions of almalinux.
It would seem the way the ISO is built changed from 8.7 to 9.x, and it is somewhat unconventional. There are likely very good reasons why it's done unconventionally. But it might be best if this approach did not cause the aforementioned command to fail.
