Why?  Do you plan to dual-boot with OS X?  ISTR you mentioned you
don't, so why go through the unnecessary hoops?  All to end up with a
filesystem for the bootloaders that you cannot write to natively too.

As the suffix indicates, one is ELF, the other is XCOFF.  Other than
that they are literally identical binary code.

On Mini G4 the XCF version exhibits a bug where it cannot load kernels
larger than a certain size, so netbsd-GENERIC.gz would boot, but
uncompressed netbsd-GENERIC wouldn't.  thorpej@ was fixing memory
management issues in this area in -current a while back, so may be
it's fixed already, I don't know.
