+Subject: [PATCH] Do not create dangling symlinks for containerized RHSM
+
+When setting RHSM into the container mode, we are creating symlinks
+to /etc/rhsm and /etc/pki/entitlement directories. However, this
+creates dangling symlinks if RHSM is not installed or user manually
+removes one of these dirs.
+
+If any of these directories is missing, skip other actions and
+log the warning. Usually it means that RHSM is not actually used
+or installed at all, so in these cases we can do the skip. The
+only corner case when system could use RHSM without
+/etc/pki/entitlement is when RHSM is configured to put these
+certificate on a different path, and we do not support nor cover
+such a scenario as we are not scanning the RHSM configuration at
+all.
+
+This also solves the problems on systems that does not have RHSM
+available at all.
