`CesmCmeps` driver fails when there are no additional restarts #472

Closed dougiesquire closed 3 months ago

dougiesquire commented 3 months ago

Running, e.g., an ACCESS-OM3 config that doesn't use the additional restarts functionality fails with:

Traceback (most recent call last):

I guess empty directories get cleaned up at some point so we need to check whether the directory exists before trying to archive. I'll follow up with a PR.
