> I've switched to that and added a hard dependency on xorriso too. Well, let's see how much havock this creates. I was prepared to give some more reasoning after having read my cheat sheet. bootinfo.txt is supposed to be what El Torito or MBR is for BIOS: The first pointer to custom boot software. Human readable, except the icon bitmap. CHRP specs [1] describe an optional MBR mock-up with a single partition of type 0x96 which spans over the whole ISO image. Not knowing about genisoimage's -chrp-boot, i implemented this in xorriso by -as mkisofs -chrp-boot-part. man genisoimage sparsely documents "-chrp-boot Add CHRP boot header." I see a CHRP pseudo-MBR in debian-6.0.5-powerpc-businesscard.iso. So most probably both options do the same. It might be that the MBR partition table is not needed for ppc64el at all. chrp1_7a.pdf 11.1.1. Media Layout Format promises to recognise ISO 9660 on unpartitioned disks.
