Motion on my RPI. I didn’t want it to save videos or photos, so I turned it off in the config. But it still saved them. So I tried a few other places in the config to turn it off, but nothing worked and I’d run out of space within a day. So I changed the save directory to /dev/null.

Then I tried to upgrade the pi, and the new version of motion has a different config, incompatible with the old one. So I’m running the old one.
