So today I discovered that there's a cron job that holds non-reproducible state that died, and now our system is fucked.
The cron job doesn't live inside any source control. This morning it entered a terminal state, and because it overwrites its state there's no way to revert it.
I'm currently waiting for the database rollback and have rewritten it in a reproducible/idempotent way.
I recommend using systemd services and/or docker compose instead. systemd services are files that describe which program / script to run and when (like after networking is active or after a certain other service is loaded).
