I like to do things just off the top of the hour, since top of the hour is when many maintenance crons run. If you’re running a modern cron daemon, you can rewrite that as:

3 1-23/6 * * * docker container restart lemmy-lemmy-1

https://crontab.guru/#3_1/6_*_*_*

Doesn’t systemd have the ability to do this as well with unix sockets?

I don’t recommend using the shell on routers for day-to-day management. Instead, consider using a network configuration management system like rconfig. I’ve used RANCID in the past, but I suspect something more modern like rconfig will be useful to you.

I subscribe to [email protected] which helps. Other than that I look for mentions of other communities in comments, similar to how I used to on reddit.

I just gave this a play-through because of your recommendation. What an adorable game! Thank you for sharing it.
