hi Luis! I notice this cron job doesn't work anymore on openpilot v0.6, any idea why? I've been using it for a long long time but updated today and now it doesnt seem to workafter updating. I also tried reinstalling this script in case the update overwrote it.
I haven't looked into this further. You are correct with the new NEOS that V0.6 uses you can no longer run cron jobs. I have not tracked down why though. The script itself still functions but it does not seem to run as a cron job anymore. In Discord a guy from comma.ai just said that its not needed anymore since openpilot automatically cycles and overwrites old videos when it gets full and now has better power management.

Hm I see....I agree that basically deleting old video files arent necessary anymore, but I really liked the shutdown script, despite power management being improved, I don't see how it could surpass turning the device off as soon as power to the car and wifi are disconnected. Can you think of any other way to facilitate an auto shutdown feature without using cron jobs? I've been looking myself but can't seem to figure anything out :/ I really liked your script haha
