The Filesystem in Userspace (FUSE) project allows you install new filesystems without touching your Linux kernel. The filesystems run as regular programs, allowing them to use shared libraries and perform tasks that would be difficult from inside the Linux kernel. FUSE filesystems look just like regular filesystems to other applications on the machine.

"The FUSE project allows you to create filesystems in userspace - which means you can create a filesystem without having to get your hands dirty and modify your kernel source. This is insanely cool, and can be used for many purposes. Here we're going to look at using the Ruby bindings to create a simple filesystem..."

Filesystem in Userspace (FUSE) has long been one of my favorite features on Linux systems. Using FUSE modules, you can mount all sorts of innovative resources -- Gmail, your Flickr photos, a remote SSH server -- directly into your local machine's filesystem and use their contents exactly as if they were normal files. Now you can do the same thing on Mac OS X, courtesy of MacFUSE.

NFS-GANESHA is an NFS version 2-4 server that runs in the user address space instead of as part of the operating system kernel. Filesystem in Userspace (FUSE) lets you run a filesystem in the user address space instead of as part of the Linux kernel, but the FUSE support in the Linux kernel from many Linux distributions does not allow you to export FUSE through NFS.

FUSE is a project that makes it easy for developers to build filesystems and virtual filesystems, by allowing their code to run in userspace, rather than at the kernel level...In this post, I’m going to round up four useful implementations of FUSE and briefly explain what each one does and how it could be useful to you.

ZFS is an advanced filesystem created by Sun Microsystems but not supported in the Linux kernel. The ZFS_on_FUSE project allows you to use ZFS through the Linux kernel as a FUSE filesystem. This means that a ZFS filesystem will be accessible just like any other filesystem the Linux kernel lets you use.

fuseiso is a FUSE module to mount ISO filesystem images (.iso files, .bin files, .nrg files..). It is also used by some other programs too such as acetoneiso2 (additional article same web site). It requires you to have fuse support in your running kernel. FUSE is fully functional file systems in a user space program.

Have you heard about ZFS? It’s a generation-defining stable high-performance high-end filesystems, created by Jeff Bonwick at Sun, and ported over to Mac OS X and the BSD family. Oh, and for Linux, using the FUSE (Filesystem in userspace) kernel abstraction. Here’s my ZFS story.

Most often, when someone talks about a filesystem or file system, they're referring to disk filesystems such as NTFS, FAT, ext2, ext3, ext4, ISO 9660 and many others but can also refer to network file systems such as CIFS (Common Internet File System aka Samba) and NFS. A filesystem is a specially-designed database of files, their disk location, definition and attributes.
