Re: fuse4bsd on kfreebsd?
PUFFS is probably nice, but emulating libfuse with librefuse has a
number of drawbacks that I discovered when porting FUSE file systems to
NetBSD. Most importantly it only tends to work for simple cases... more
advanced libfuse functionality is unsupported, so it can only support a
subset of the FUSE filesystems that are out there.
So I think that FUSE is the way to go. It seems to work well enough in
7.x/8.x and as it has been in the ports tree (together with a number of
FUSE file systems) for some time now it's probably more mature than the
PUFFS port which doesn't even seem to be in FreeBSD at all yet.

I wouldn't waste time on fuse4bsd, it is a dead project. PUFFS looks
much more promising.
PUFFS is included in NetBSD (http://www.netbsd.org/docs/puffs/), and
has been recently ported to FreeBSD (see
It has a compatibility layer (librefuse) to make it FUSE-compatible.

wishlist against libfuse-dev.
With that file symlinked to fuse4bsd-hg/fuse_module/fuse_kernel.h, it
fails to build after a while with the following error message:
fuse_dev.c: In function `fusedev_clone':
fuse_dev.c:551: error: implicit declaration of function `unit2minor'
This seems to be a change in FreeBSD 8.x, other software (e.g. zaptel)
patched it by replacing "unit2minor(unit)" with just "unit" for
FreeBSD> 800062 or so.
My patches so far:
All changes are made plus many more are already made in FreeBSD's
sysutils/fusefs-kmod port. So I took all the patches from there and
came much further.
Now it ends with this:

fuse_vnops.c: In function `create_filehandle':
fuse_vnops.c:1586: error: `struct fuse_open_in' has no member named `mode'
*** Error code 1
Anyway, this is still the fuse kernel module. I couldn't find it in
the modules on disk or those listed with lsmod. So I guess we'll need
that for using FUSE und kbsd anyway and not just only the tools.
That's all for today. :)
