+## Q: What happens when I use `rpm-ostree override replace` to replace an RPM?
+
+When a package is replaced in this fashion, it will remain in place through any subsequent upgrades.
+
+While this can be helpful for short-term fixes, it is important to remember that the package replacement
+is in place, as the cluster currently has no mechanism for reporting that the node has been changed in this
+fashion.  This kind of package replacement can also leave your nodes exposed to potential problems
+that are fixed in newer versions of the package.
