I'm sure Bill's already replied, but just in case he hasn't, there are a
lot of things wrong with it, actually. But, the major one is that GPL'd
code may not be included in the same binary with non-GPL'd code unless
you're willing to distribute the non-GPL'd source. So, although we do in
fact have GPL'd code in the NetBSD source tree (gcc being one of the more
important parts), we _cannot_ have GPL'd code in the kernel source.
Apparently, doing this (i.e. hfsfs) as an LKM is a way around this, since
the LKM is not compiled into the kernel.
>From what I've read (and there are enough flame wars over licensing that I
hope this doesn't start another), the basic problem (from the NetBSD
perspective), is that GPL'd code requires that all derived works
distribute source, whereas the BSD license doesn't.

I think the utilities are truly free (if you can call the GPL free). I
think that Bill was using a slightly different route, based off of the
hfsfs vfs module...
