 #       not available or patched out by upstream. These are potentially packages

+# custom: Specifically added packages that are custom, and probably needed for
+#         some reason or another. This is generally very rare. For example,
+#         CentOS had centos-obsolete-packages. We thought it was a good idea
+#         and brought it in as "rocky-obsolete-packages".
 # previous: These are previously patched packages that are no longer patched in
 #           Rocky as they are upstreamed or it was found no longer required.
 # provides: These are specific branded packages that provide something else
