HFS+ support?

HFS+ support?

[Brian Kidder]

I know Apple's new HFS+ (aka HFS Extended) filesystem isn't currently
supported in 2.2 (and apparently 2.3).  However, I've been able to
find essentially zero information about HFS+ for Linux other than that.

Are there current efforts to make this filesystem available?  If so,
where can I find more information and possibly assist?  If not, what's
the right way to start such an effort?

I currently have a PowerBook running linuxppc-1999, and would very
much like to gain access to the Mac-side of the drive (no, going back
to HFS isn't the right answer).  I am not that familiar with the
filesystem guts of linux or the HFS module, but I'm very willing to
dive in and try.

Thanks for your help, and continuing efforts to make linux great,
-Brian Kidder

I believe that Apple has released some documentation on HFS+, I don't 
know if its enough to write a driver or not.  another possibility 
would be for someone to document HFS+ by using the APSL code that is 
part of Darwin, then someone else could write the driver.  (to avoid 
the risk of infecting GPL code with APSL code.)

Have Apple put out any HFS+ documentation yet ?

Yes (updated in March 1999)

Technical Note 1150 does provide enough information (aparently)
to write support for HFS+:

http://developer.apple.com/technotes/tn/tn1150.html

Darwin OS source code (from http://publicsource.apple.com/)
contains a working HFS+ file system implementation that can be
used as a reference in case of lacks in the documentation.
