[Gluster-devel] NetBSD support, FUSE

[Emmanuel Dreyfus]

Hello

I gave a try to glusterfs on NetBSD. That produced a few patches (see below),
and the server seems fine. The client is another story, though.

NetBSD has a library-level FUSE API, but not a kernel-level API. The library
remaps FUSE to NetBSD's native FUSE equivalent (PUFFS).

After a tour in the code, it seems glusterfs just open /dev/fuse and work on
that, so it will not work. Anyone can confirm there is no support for
library-level FUSE?

The patches:

1) The == operator exists only in bash. POSIX compliance require = instead:
