 > The two reboots described below are not optional. During installation, the initial boot into hyprland will provision the required sddm user. This is a one time step, all subsequent boots will succeed.

-  ```
+  ```sh
   systemctl reboot
   ```

-  ```
+  ```sh
   rpm-ostree rebase ostree-image-signed:docker://ghcr.io/heus-sueh/$IMAGE_NAME:latest
   ```
