 During upgrades, the contents of `/release-manifests` are applied in order, exactly as `ls` would

 A few special optimizations are applied above linear ordering - if the CVO sees two different

 Some operators need to run at a specific time in the release process (OLM, kube, openshift core operators, network, service CA).  These components can ensure they run in a specific order across operators by prefixing their manifests with:
 
-    0000_<runlevel>_<dash-separated_component>-<manifest_filename>
+    0000_<runlevel>_<dash-separated-component>_<manifest_filename>
 
 For example, the Kube core operators run in runlevel 10-19 and have filenames like
