Cron must do something like this, it's not dumb, it's a program really
mature and should have this.

My only concern is that this adds latency to the process (cron ->
shell ->program), but we need to gather use cases to see if it's
acceptable or not. My guess is that it's acceptable.

But as already told, we should have an easy-to-use API to avoid
writing to crontab directly.
