Firmware update does not report success.

Firmware updates do not properly report success. Instead the page will fail to load or a HTML 500 error is received. The success/reboot message is then reported after the firmware was already applied and the system rebooted.

Reboot seems to happen to quickly for the request to return.

Templates changing with an update results in the jinja2 template engine failing this will result in a 500 error code. Additionally the reboot fork was to fast and sometimes there would not be time for the redirected page to load.

Fixes are in 2.2.0, unfortunately these fixes only take effect after it is installed.
