[ANNOUNCE] Filesystem in Userspace (FUSE) 1.1 stable version

[Szeredi Miklos]

This release adds support for the 2.6 Linux kernel series.  Other new
features include support for exporting FUSE filesystems over NFS, read
efficiency improvements, automatic lazy unmounting, the addition of
the fsync call, plus minor bugfixes and cleanups.

About:

FUSE is a combination of a kernel module and a userspace library that
makes the creation of filesystems in userspace very easy.  A "Hello
World" filesystem implementation is just 59 lines long (excluding
empty lines and comments).

There are currently a number of applications using FUSE in the
following categories: exporting internal state of devices (OWFS,
SieFS), exporting existing userspace virtual filesystems (KIO - FUSE
gateway, AVFS), network filesystems (SMB for FUSE, FunFS), encrypted
filesystems (EncFS, PhoneBook), exporting internal data of
applications (Run Time Access).  For more info about these see
'Filesystems' in the distribution.

In addition to the native C API, FUSE has bindings for a number of
other languages: Perl, Python, Java and C++.

FUSE was designed with the following goals in mind: very simple
userspace API, generic, efficient (but still simple) kernel API and
ability for non-root users to create and mount filesystems securely.

Future plans:

I plan to submit the next version (with a revised user - kernel
interface) for inclusion into the 2.6 and/or 2.7 kernels.  Still to do
is a modification of the mount syscall to allow non-root users to
mount FUSE filesystems (currently done with a suid-root helper
program).

Comments, flames, patches, bugreports are welcome!

Any connection here with making linux fs easier to learn?

I ask because I've not found any reasonably quick way of making sense
of:

http://lxr.linux.no/source/fs/udf/

developed at:

http://sourceforge.net/projects/linux-udf/

I see I can trivially make that fs fail fsck and patch fs/udf to teach
gdb to print the structures on disc.  I see less trivially I can
persuade that fs to read back what I did not write.  But as yet I have
not more directly helped improve the fs/udf/ code.

Thank you from that I found:

the AVFS project page on sourceforge
http://sourceforge.net/projects/avf/

AVFS - A Virtual File System
http://www.inf.bme.hu/~mszeredi/avfs/

Also I see this FUSE is not sourceforge.net/projects/fuse/.

Not really.  FUSE and the linux VFS have not much in common except they
both have a similar set of operations (open, read, write, mkdir,
unlink, etc.).  But linux VFS is much more generic.

Yeah, a working UDF implementation would be good.  It's very easy to
prototype such an FS in FUSE.  Any takers? ;)

The homepage and SF project page of AVFS and FUSE are a mess.  Sorry
about that.

That is true.  the name FUSE turned out to be unfortunate, because
it's an often chosen project name.

Nothing begun already?

Probably not.  I haven't heard of such a project.
