// systemd's own directory (tmpfiles.d/systemd.conf: d /var/lib/systemd 0755 root root); the node-engine gave it to
// the operator's account, mode 0700, on every machine. What the tools keep moves to the mesh's directory for the
// module, and for one delivery the record "state" states the package's owner and mode, so the node-engine, which
// takes a directory it recorded at the same path under the same id as its own, gives it back.
