Which is the homeassistant docker container. It is filled with stuff that looks awfully similar to the hass logs… Here’s a snippet:

Anyhow, I deleted it and had to reboot the machine to get it to release the file handler and the associated space, but now I have 67GB more free space.
I would still like to know the right way to set up pruning for it though.
Or if it’s just a duplicate of the homeassistant log, just to turn it off, as I already have one log… It’s plenty.
