Thanks for this - I'll include some sentences mentioning how this works
(and possibly a method call to daemonize the process) in the next
release of FuseFS.

The IO.select loop is intended to hang the script indefinitely. The
kernel communicates with the script through a socket opened on
/dev/fuse, and that socket is what IO.select is waiting for input on.

The proper method way to do this is either:

1) start the script, then play around with the FS in another terminal

or 2) start the script in the background, then play with it.
  ruby sample/yamlfs.rb mountpoint someyamlfile.yaml &

Hope that helps.
