I’ve just created a RPM of dmg2img for the x86_64 version of Mandriva 2009.1. The package is available in my RPM repository.
dmg2img is a command line utility to extract the content of an Apple Disk Image .dmg file. Here is how I use it to access content:
dmg2img ./my-package.dmg mount -t hfsplus -o loop ./my-package.img /media/my-mount-point
