For what it's worth this will not work properly, you have different environment variables for user and system units. Proper error handling and graceful fallback for these cases are probably worth a module here (though it could be a 10-20 liner instead too).

Really? I thought the point of the environment variable was it was the same, and the directory it pointed to differed depending on the service type.

I'd love a reference since at least for every systemd version I've used, you're wrong.

That's application specific, so it can't really fit in a generic library well.

I must've had it confused with StateDirectory[0]. Thank you for pointing my mistake out. That does make the library a bit less useful.

		StateDirectory looks like it's also always the environment variable 'STATE_DIRECTORY', regardless whether it's a user or system unit, right? `systemd-run -p StateDirectory=test -t sh -c 'echo $STATE_DIRECTORY'` works fine with both `--system` and `--user`, so seems like that's the same too.
