Description of problem: Starting with the Fedora-Rawhide-20220616.n.1 compose the Server ISO is not bootable, thus I suspect something related changed in lorax. The netinst ISO boots OK. Everything was OK up to Fedora-Rawhide-20220615.n.0 https://openqa.stg.fedoraproject.org/tests/1921915#step/_boot_to_anaconda/3 is screen from a recent ISO. Like the grub binary would be completely missing from the ISO. When trying to open Fedora-Server-dvd-ppc64le-Rawhide-20220719.n.0.iso in Midnight Commander it complains about "isoinfo: Unable to find Joliet SVD" (and doesn't show any directory structure), but Fedora-Everything-netinst-ppc64le-Rawhide-20220719.n.0.iso opens OK (showing the directory structure). Could the grafting go wrong in recent lorax? Version-Release number of selected component (if applicable): lorax-37.5-1.fc37

The DVD is created by pungi adding content to the boot.iso, and in rawhide pungi is using xorriso to 'pass thru' the boot config so I'm guessing this doesn't work right for ppc64le.
I tracked this down to xorriso needing to add the -U command (long filename support) when replaying the iso. I've got a PR for this in mkksiso here: https://github.com/weldr/lorax/pull/1251 And commented in the pungi PR: https://pagure.io/pungi/pull-request/1613
Huh. I thought I already reported this somewhere, weeks ago, but can't seem to find it right now.
Oh, there it is. *** This bug has been marked as a duplicate of bug 2102907 ***
