I don't think this is for GNUStep to support, but for (a utility running on) 
the underlying operating system.

UDRW is just a raw disk image and there are existing easy ways to attach them 
to device files and/or mount them on Linux, FreeBSD, etc. (e.g. mount -o loop 
on Linux is one way).

Most other modern Apple disk image formats are of the form <data>, followed by 
some XML, followed by 512 bytes of metadata, e.g. <data> is:

- UDRO: raw disk image as for UDRW - so should be mountable/attachable in the 
same way as a UDRW
- UDBZ: raw disk image compressed with bzip2 (the entire disk image is 
compressed as a whole)

etc. I don't know if there is support to attach such files / loop mount such 
files on Linux etc. at present. I can't imagine it would be hard to do, though.
