Any idea why sccache fails?

Did you look at the test? Maybe you have to adapt he location at this line:

Looks slightly better now, two tests are still failing. Do you agree that moving the cache out of tree is a good idea?

Let's see how far we get with the current implementation after #217. I still think the cache shouldn't live inside the worktree, let's discuss when this becomes an issue.
