The original 14 days was too short. When having 180 days preservation
period, then it is around 13 notifications for a chroot.
With 60 days interval between notifications, it is 3 notifications
per chroot (one straight away, the second one at day 60, and the
last one at day 120). Another considerable option would be like 55 days.
This way we would get one more notification about two weeks before deletion.
