A BSD disklabel would be inappropriate since Apple uses the Macintosh 
partition format.  If the Linux kernel's UFS driver requires UFS 
partitions to be on disks partitioned with the BSD disklabel scheme, I 
think that would qualify as a bug -- FS drivers are supposed to be 
partition scheme neutral.

I have vague memories that there are supposed to be some flags you can 
pass to the Linux mount which allow it to mount an Apple/NeXT UFS.  
This because it's not quite a standard UFS format; NeXT let their UFS 
implementation drift away from other BSDs back when NeXT was getting 
out of being an OS vendor.  MacOS X UFS is still neglected since HFS+ 
is now the primary FS.
