Typescript: Error with watch mode in Windows 10 ubuntu bash

[emilekberg]

TypeScript Version: 2.0.0 (@beta)
Trying to use bash in Windows 10 for all my development. When running tsc -w on a Project with a tsconfig.json i get an error. This error exists even on an empty Project.
Expected behavior:
tsc -w should build the Project as normally. tsc works fine
Actual behavior:
an error is thrown:

emilekberg@ALDERAAN:/mnt/e/dev/test$ tsc --init
message TS6071: Successfully created a tsconfig.json file.
emilekberg@ALDERAAN:/mnt/e/dev/test$ tsc --w
fs.js:1431
    throw error;
    ^

This doesn't really look like a TypeScript issue -- we're just calling fs.watch. What happens when you run require('fs').watch('/mnt/e/dev/test') from the node REPL?

[emilekberg]

You seem to be correct, the same behaviour is met.

emilekberg@ALDERAAN:/mnt/e/dev/test$ sudo nodejs
> require('fs').watch('.')
Error: watch . EPERM

Is this a config issue with what bash can access or? I tried with sudo as well, same result.
