It might still be useful as a reference for old systems, so let's keep it.
A bit simpler, and self-contained solution with no extra files. This is based on systemd timers and services, so it is has a smaller footprint on systems which already have systemd installed (cron and logrotate dependencies are gone). I assume that ansible is mostly used with modern systems which have systemd available. Systemd will restart the service every OnUnitInactiveSec=, while making sure to not schedule overlapping runs. In practice, it is convenient to change the timer to something as low as one minute when quick updates are needed. With --only-if-changed the load on the system is not even noticable because all that happens is a noop git pull if no changes were made to the repo. The logs end up in the journal, so no logging configuration is necessary.

instead of 'convert', add this as another example |

I wrote "convert", but the PR really doesn't remove the old example. The old file is renamed, and a new one is added, i.e. both examples are still in tree. I think it is appropriate to make the new example "the default" because it is more lightweight and appropriate for modern systems. |

Ah, fair enough, missed the 2nd file was preserving the cron version. |
