+* cgroup-agent: downgrade error messages
+
+* document systemd-journal-flush.service properly
+
+* chane systemd-journal-flush into a service that stays around during
+ boot, and causes the journal to be moved back to /run on shutdown,
+ so that we don't keep /var busy. This needs to happen synchronously,
+ hence doing this via signals is not going to work.
+
+* allow implementation of InaccessibleDirectories=/ plus
+ ReadOnlyDirectories=... for whitelisting files for a service.
