One thing to note is that we currently have a systemd timer unit that does a ‘snap refresh’ once a week. This was placed there when we moved to using the internal timer, in case things got stuck; a system administrator that wants to have refreshes happen on a longer cadence than weekly needs to modify (or disable) this file. A systemctl disable snapd.refresh.timer would accomplish the latter.
There is still value in having this systemd timer as a a fallback, in case a bug betwen snapd and the system clock result in snapd’s refresh timer not working, but snapd needs some changes to be more aware of this.
This’ll also let us stop it looking weird in the changes log.
