Several image formats are supported by Apple's utility, and they have different properties. The images support native compression (zlib), as well as various filesystem formats (hfs, iso, hfs+), and even encryption. The file format is called UDIF (Universal Disk Image Format), and to the best of my knowledge the only tool that works with the format is apple's 'hdiutil'. For information on the tool and the format, see: http://www.hmug.org/man/1/hdiutil.html Unfortunately, the utility is not part of Darwin (the open-source part of the system); it's only included with Mac OS X. Thus, you have little chance of finding a port for Linux. Of course, you can always burn the .dmg file onto an ISO9660 disc; any mac you put the disc in will be able to mount the image off of the CD. However, you won't have direct access to the image, which you might want if you need to boot directly off of a CD. Finally, if you have access to the mac, you can always use it to convert the image into ISO, and then copy it to your linux box to burn. Obviously, this is only useful if you have a mac with no CD burner; otherwise you would just burn the CD from the mac!
