Hi Rumen,

the error message is actually expected in this case. Since the VFS in
this example is static (i.e. immutable), fs_query fails to set up a
watch handler. However, it still outputs the directory listing
correctly. If you change the '<vfs/>' into '<vfs><ram/></vfs>' to make
the VFS mutable, the error message will disappear.

Cheers
Johannes
