Upgrading when space seems low: stop app, then cleanup, then rebuild app?

So yeah, if your disk space is so tight that you don’t have room for two images, then you need to destroy all of them before building a new one, which puts you in a bad way if for some reason you can’t build a new image. If that’s the case, you really need more disk space. The easiest thing to do is move backups to S3.

I’m surprised by “disk space is so tight” in my situation. I run cleanup, I have 7.9 GB free, then I run ./launcher rebuild app and it refuses to finish. Is 7.9 GB free when I want to rebuild the app really so little?!

(UPDATE: Now I understand how this can happen. I leave this here for Innocent Bystanders to find in a web search. Please read this entire thread, folks!)
