+ ``cephadm`` stores a local copy of the ``cephadm`` binary in
+ ``var/lib/ceph/{FSID}/cephadm.{DIGEST}``, where ``{DIGEST}`` is an alphanumeric
+ string representing the currently-running version of Ceph. In the Squid and
+ Reef releases of Ceph, this ``cephadm`` file is stored as a zip file and must
+ be unzipped before its contents can be examined.
+ 
+ This procedure explains how to generate a list of the default container images
+ used by ``cephadm``.
+ 
+ .. note:: This procedure applies only to the Reef and Squid releases of Ceph.
+    If you are using a different version of Ceph, you cannot use this procedure
+    to examine the list of default containers used by cephadm. Make sure that
+    you are reading the documentation for the release of Ceph that you have
+    installed.
