rerooted FS missing some functions

[neerolyte]

I'm not sure if I'm doing it wrong (an example in the docs would be great), but when I simply reroot() a FS the rerooted version is missing some functions, e.g.:

var FS = require('q-io/fs');

function checkFuncs(obj) {
    checkFunc(obj, 'makeDirectory');
    checkFunc(obj, 'makeTree');
}
function checkFunc(obj, name) {
    console.log(name + ": " + (obj[name]?"exists":"missing"));
}

console.log("Main FS:");
checkFuncs(FS);

FS.reroot('/')
.then(function(fs) {
    console.log("Rerooted FS:");
    checkFuncs(fs);
});

produces:

$ node rerooted_test.js 
Main FS:
makeDirectory: exists
makeTree: exists
Rerooted FS:
makeDirectory: missing
makeTree: exists

This causes problems in places because if I call makeTree() on a rerooted FS it fails because it will eventually call this.makeDirectory() internally (which isn't a function).

So am I doing something wrong or is this just a bug?

It’s a bug, thanks.

You might check again and please let me know if you encounter further missing methods.
