// The same one-click update the console page drives, for the two cases a page cannot
// serve: the process is not running at all, and somebody is ssh'd in with a keyboard.
// Keeping it in the binary rather than only in a shell script means one implementation of
// "fetch, fast-forward, rebuild, swap" instead of two that can disagree. The update
// source is read from the same config.yaml field the page saves to, so the keyboard and
// the button can never update from different repositories.
