+Subject: [PATCH] systemd: put cloud-init.target After multi-user.target
+
+When we moved cloud-final.service to run After multi-user.target it
+caused a dependency loop (as cloud-init.target was still implied to be
+Before multi-user.target).
+
+journalctl would either show:
+  cloud-init.target: Breaking ordering cycle by deleting job
+     cloud-final.service/start
+or
+  multi-user.target: Breaking ordering cycle by deleting job
+     cloud-init.target/start
+
+The fix here is to clearly state that cloud-init.target is also
+  After multi-user.target
+
+LP: #1623868
