bzr branch lp:libisofs/for-libisoburn (to become libisofs-1.3.0.tar.gz)
===============================================================================
* Bug fix: Unspecified Expiration Time and Effective Time of ISO volume was
represented by 0-bytes rather than ASCII '0' digits.
* Bug fix: Reserved and unused fields of APM entries were not zeroed.
* New option bits with el_torito_set_isolinux_options() and
iso_write_opts_set_system_area() to control GRUB2 patching of
boot image and MBR.
* New API calls iso_image_set_sparc_core() and iso_image_get_sparc_core().
* Bug fix: Unspecified Expiration Time and Effective Time of ISO volume was
represented by 0-bytes rather than ASCII '0' digits.
* Bug fix: Reserved and unused fields of APM entries were not zeroed.
* Bug fix: GPT header CRC was computed from all 512 bytes rather than from 92.
* Bug fix: The protective MBR partition for GPT started at block 0 instead of 1.

CHRP is marked by an MBR partition entry of type 0x96 spanning the whole
ISO 9660 image.
The specs in chrp1_7a.pdf promise that CHRP also recognizes ISO 9660 file
systems on unpartitioned disks. (See 11.1.1. Media Layout Format)
Vladimir Serbinenko stated:
PReP boot may be preferable. At least it can co-exist with other partitions
in the ISO image.
in the ISO image [without causing overlapping between partitions].
