Comment 2 for bug 1362752

I have tested my patch and it works as expected here.
I copied Rohan's method from this file: https://bazaar.launchpad.net/~ubuntu-branches/ubuntu/utopic/casper/utopic/view/head:/scripts/casper-bottom/15autologin for the sake of consitency.

This makes the indentation a bit ugly, but the rest of the script is not much prettier imho.
