That's a fake Block0 of an Apple Partition Map. Part of mjg's layout. Caused by isohybrid option --mac or xorrisofs option -isohybrid-apm-hfsplus. * Fedora has it with EFI FAT filesystem in one partition

I'm going to get the hang of this mailing list eventually.

(Except the known bugs which affect Linux binaries, too.) Not really. I had never found a convincing source for it and had seen previous list entries like this

Hi, following will be 6 patch proposals for isohybrid.c 1: Encode GPT partition names as UTF-16LE 2: Correct blocking factor in APM partition block counts 3: Correct end block address of first GPT partition 4: Write GPT backup to the very end of the image 5: Change all fseek(3) to fseeko(3) 6: Introduce option --mbr and make isohybrid.c compilable standalone If the form needs adjustments,
