library. It follows the wire protocol closely, but provides
convenient abstractions for building both node and path based file
systems
zipfs/multizipfs.go shows how to use in-process mounts to
combine multiple Go-FUSE filesystems into a larger filesystem.
fuse/loopback.go mounts another piece of the filesystem.
Functionally, it is similar to a symlink. A binary to run is in
example/loopback/ . For example

Appendix I. Go-FUSE log format
To increase signal/noise ratio Go-FUSE uses abbreviations in its debug log
output. Here is how to read it:
iX means inode X;
gX means generation X;
tA and tE means timeout for attributes and directory entry correspondingly;
[<off> +<size>) means data range from <off> inclusive till <off>+<size> exclusive;
Xb means X bytes.
Every line is prefixed with either rx <unique> or tx <unique> to denote
whether it was for kernel request, which Go-FUSE received, or reply, which
Go-FUSE sent back to kernel.
Example debug log output:
