Frontail on Dietpi with Openhab2.5

I think it might be worth reporting this on the DietPi forum, as I’ve just seen this same behaviour on an ODroid C2 and C4.

However, only running 1 log file in the service file, it will work perfectly.

Likewise, running the full command from a prompt works perfectly.

I’ve also just fired up Ubuntu 20 on a C4 and the service file you have above works perfectly.
