+    InternalTLSNbdCAFile, InternalTLSVncCAFile and InternalTLSQemuCAFile
+    do not point to the default IPA ca.crt file and instead are requested
+    to be loaded to component specific CA files (even if they are the same).
+    This can lead to a race where the CA cert is not being written by
+    certmonger in time.
+    Ib868465c20d97c62cbcb214bfc62d949bd6efc62 already changed the default to
+    use the IPA system cacert file '/etc/ipa/ca.crt' per default starting with
+    the wallaby release using the ansible role. This change backports to also
+    use the IPA system cacert file '/etc/ipa/ca.crt' to previous release when
+    managing the certs via puppet-tripleo.
