"Apple_HFS" is the partition type of the first payload partition
entry in the Apple Partition Map. Written by genisoimage at
byte offset 1072 of the ISO image.

The field has a size of 32 bytes. So you could overwrite it by
other texts in order to check whether they cause less complaints.

My knowledge about APM stems from
    http://opensource.apple.com/source/IOStorageFamily/IOStorageFamily-116/IOApplePartitionScheme.h (typedef struct Block0)
    http://www.informit.com/articles/article.aspx?p=376123&seqNum=3
and is summarized in
    http://bazaar.launchpad.net/~libburnia-team/libisofs/scdbackup/view/head:/doc/boot_sectors.txt
    in chapter "Apple Partition Map"


(Any further knowledge about HFS w/o "+" is welcome. I am still
 interested in exploring the HFS aspects of Debian powerpc images.
 I am subscribed to debian-cd@lists.debian.org but not to
 debian-bugs-dist@lists.debian.org)


Have a nice day :)
