+    Check for leftover repository configuration files from a cldeploy conversion.
+
+    These repofiles, also known as "base repos" in the cldeploy context, are
+    used to bootstrap the CL systems during the conversion process.
+    Normally, they are removed by the cldeploy tool itself, but in some
+    cases, they may be left behind.
+    If that happens, they can cause problems with the upgrade process,
+    since neither leapp nor the upgrade process itself expect them to be present.
+
+    This actor checks for the presence of these files and warns the user to remove them if found.
+
+    The files are located in the /etc/yum.repos.d directory and have names based on
+    the URL of the repository they point to. For example:
+    repo.cloudlinux.com_cloudlinux_8_BaseOS_x86_64_os_.repo
