Currently, it has none which results in logspam on start like Could not load the spec: Error: ENOENT: no such file or directory, open '/srv/deployment/tilerator/deploy-cache/revs/b50104637b2854db66f62c6ef157aa7a0be08fc7/src/spec.yaml'
While Tilerator has no publicly available HTTP interfaces, does it make sense to add a check to e.g. verify that tile generation still works?
