It started with the D drive.

It started with the D drive.

Remember? Games on D, documents on D. C drive - for the system, format it every six months. A colleague of mine went further: configured Windows once, took a disk image, and after formatting just restored it. Not reinstalling - restoring.

That was twenty years ago. We call it “containers” now.

Same idea: data separate from executables. Except now the OS itself became the “executables”. Spin up a new image - everything works.

So why are you still running do-release-upgrade on k8s nodes?

Drain the node. Flash a new image. Bring it back. That’s not an upgrade - it’s a replacement. Much cleaner.

Not the process — the result.
