Nix: Upgrading Ubuntu

I recently discovered that my Linode box was running a fairly old version of Ubuntu. Because it is a remote box that I SSH into, there is no graphical user interface. Upgrading to a newer release can be accomplished with the following command line utility:

do-release-upgrade

It includes a series of prompts regarding choices about the upgrade and a lot of waiting.

Adding the -d flag will upgrade to the latest development release.
