Can't install Discourse with only 10 GB disk, run out of space

Should there be some guidance in the 30-minute installation guide about aufs? Right now it assumes DigitalOcean, but folks may want to install on other hosts, for whatever reason.

I am pretty sure launcher warns about non aufs these days.
