Disallow jumping back in time per default
Ok, so a couple of servers had drifted because of a dns issue, so I read up on chrony config, to ensure they didn't do any jumps back in time.
I managed to make it work on one server. On the other however, I had to install chrony for the first time.
And lo and behold, after apt install chrony, the server had jumped back 30 minutes.
Apparently because:
- Ubuntu enables the daemon immediately
- default config doesn't prohibit jumping back in time
Would it make sense for Chrony to tackle the second point per default, to avoid this scenario?
