 ### How to try it out
 
-You can actually do this in mock pretty easily. You could also probably get
-this running in a podman container or otherwise. As of this writing, we

+You can run this on a running system, in a mock root, or a podman container. In
+fact, most builds may fail in mock due to loop devices being unusable.
 
 **Note**: SELinux must be set to permissive.
 
 **Note**: There may be cases where a build will fail in mock. If this is the
 case, you will need to use `--isolation=simple`.

+**Note**: If you receive an error about loop devices while running in mock, run
+this outside of mock instead.
