Bug#620916: grub-mkrescue: ISO images bootable as disk (like isohybrid) but not mountable within Linux

[Josh Triplett]

Package: grub-common
Version: 1.99~rc1-8
Severity: normal

grub-mkrescue creates .iso images which include a magic hard disk
partition table and boot sector at the beginning, making them work
either as a bootable CD or as a bootable USB disk, like isohybrid disks.
However, unlike isohybrid disks, the disk images built by grub-mkrescue
will not mount on a normal Linux system.  dmesg says "ISOFS: Unable to
identify CD-ROM format.".
