"NFS-GANESHA accesses the underlying data through a File System Abstraction Layer (FSAL), allowing you to plug in your own storage mechanism and access it from any NFS client. NFS-GANESHA provides a FUSE-compatible FSAL to allow you to quickly access a FUSE filesystem over NFS while avoiding the need for data to bounce through the kernel FUSE mechanism on the NFS server.
"Why would you want to do this? Running a filesystem out of the kernel through FUSE lets you use libraries to support your filesystem's functionality -- for example, you can use Berkeley DB to store the file contents -- and also aids greatly during the development of your filesystem because a bug in your code won't cause the kernel itself to oops. FUSE includes a portion that runs inside the Linux kernel, which allows applications to use FUSE filesystems just like any other "regular" kernel filesystem. The Linux kernel FUSE code communicates with the user address space FUSE filesystems on behalf of the application whenever you use a FUSE filesystem. One downside of all of this is that some FUSE filesystems don't like being exported over NFS."
