-* RemoveIPC= in unit files for removing POSIX/SysV IPC objects
+* introduce an "invocation ID" for units, that is randomly generated, and

+  we traverse inactive → activating/active, and should be the primary key to
+  map offline data (stored in the journal) with online bus objects. Let's pass

+  the cgroup of a services. The former is accessible without privileges, the
+  latter ensures the ID cannot be faked.
