It quite arguably is a filesystem. It's just not *a* filesystem but
a hook for arbitrary filesystems.
Moreover since it affects the stability of the OS, and isn't
anywhere ready for prime time nor is it likely to ever be ready for
production, again in part b/c by nature it's a userspace "thingie",
this would still be anathema.
From what I understand the idea is to remove all the potentially
unstable stuff out
of kernal space. The kernel driver could then concentrate on being
more fault
tolerant. If a user space driver crashes, then like an application
that's all that
goes down.
If you are interested, there is an interview with Amit Singh here:
http://www.itconversations.com/shows/detail1804.html
where he discusses MacFuse and why he started the project. Part of
the reason he
cites is that this approach vastly simplifies the work of writing a
reliable
file system driver.
I mean it's a nice thought, but given that it's supposed to be
userspace, that the kernel and core OS are quite clearly kernel-
and system-space, that it's not prime time ready, currently and
probably always unstable by nature, and always going to be more
appropriately implemented at a user level that it doesn't belong as
part of the systems. If it did would it not then be MacSUSE? And
my, oh my, wouldn't that they get confusing with something else by
that name ;)
In many ways USB isn't that much different. There are kernel
components, but
there is also much that is done in user-space. When I asked the
question it
wasn't so much a question of whether it was ready for prime time. I
am more
interested, in finding out whether it could have a reasonable place
as part
of the system architecture, if it got the necessary focus.
The development of the MacFuse also shows ways in which Darwin/MacOS
X needs
improvement. One minor area is in the way that URL handlers are
registered
with the Finder - they are currently in a form which does not permit
extension (see /System/Library/URLMount), so only the standard Apple
file systems can benefit from this.
