I'm not talking about reading logs. (Which, by the way, is a lot easier to do in a dead system when they're text and not binary. It's hard to mess up cat, grep, and notepad.)

I'm talking about being able to rule out causes because the primary components of the system are independent of each other.

The binary format doesn't matter for browsing logs. Replace `cat /your/custom/service/file.log | grep ...` with `journalctl -u service | grep ...` (or just `-a` for everything)

I'd actually argue it's easier not to mess up with journal with simple tools, because you don't have to special-case `service`, `service.1`, `service.2.gz` files.

For a dead system with it's main disk mounted on a living one, on which the service is not registered, is it that easy?

I've never tried.

I like service files, but the rest not so much.
