Re: [ANNOUNCE] HFS+ driver

Just as a note, I've removed linux-kernel from the cc: list, since it
seems like we've wandered off anything of general interest...

I guess I should write some documentation.  :)

Well, HFS+ does allow 255 character filenames, but some versions of the
MacOS will choke on anything longer than the old limit. I haven't tried
any UFS filesystems on any of my Macs. I have some pretty strong comments
from people inside Apple warning against trusting their implementation
of UFS, which kind of scared me off of it. The official word out of Apple
seems to be to use HFS+ unless you have a really, really good reason.

Always a good idea...

That's where I originally put it, but then a new filesystem showed up
and I didn't pay close enough attention to the merge, I guess.

That would have to be in the code from Roman. I'm not quite done reading
it yet, I must admit. I've been busy with other stuff.

However, I have tended to keep the code clean for as many versions
as possible. There was one major change that keeps really old 2.4.x
versions from being easily source compatible without the horrible
KERNEL_VERSION hacks, and I'd like to avoid such hacks if possible.

I'll take a look when I get a chance. Thanks for taking an interest
in the project.
