 ### Improvements {#improvements-2-1-3}
+* During `install` and `join`, permissions for the data directory are set to 755 to ensure successful operation.
+* Adds a preflight check to verify execute permissions on the data directory and its parent directories. This prevents installation issues, including etcd permissions issues.
 * The following kernel parameters are configured automatically: `fs.inotify.max_user_instances = 1024` and `fs.inotify.max_user_watches = 65536`.
 * Adds a preflight check to ensure the following kernel parameters are set correctly: `fs.inotify.max_user_instances = 1024` and `fs.inotify.max_user_watches = 65536`.
 * Surfaces better error messages during the installation if the node is not ready.
-* Adds a preflight check to verify execute permissions on the data directory and its parent directories. This prevents installation issues, including etcd permissions issues.
