systemd execution terminates

[wm-ax]

This update causes the start script to "exit gracefully" on non-interactive execution so that the app is not served.

Specifically, it seems that a statement process.stdin.on('end', f); triggers the invocation of f when the code is run e.g. through systemd. (Why would non-interactive execution cause process.stdin to act as though it has read an EOF?)

Anyway, it would be nice to be able to run the start script through systemd (without just commenting out the offending block).
