ssh-keygen doesn't work with -Hu www-data

[aronwoost]

First let me say, big thanks for this project. Although I didn't use much of the move stuff, it's the perfect tutorial to get a node app on EC2 up and running!

I only noticed, that when generating a key in behalf of www-data $ sudo git pull doesn't seams to work. The key can't be found, since ssh looking in /root/.ssh/ for the key.

When just doing sudo ssh-keygen -t rsa everything is fine.

Or did I miss something?
