Thanks for this snippet. On TrueNAS-12.0-U8.1 re-mounting root / writeable is not necessary.

I just want to mention, that you have to set /usr/local/bin/check_mk as a POST-INIT service in the GUI.

However, the smart plugin does not seem to be executed as the agent is not really aware of the paths when you install it this way.
