I found this default setting in `/etc/apt/apt.conf.d/02-armbian-periodic` for apt in my armbian image for my odroid HC2: ```APT::Periodic::Enable: "0"``` I suspect many credit-card servers just chug along with default settings for years without manual upgrades (myself included until i reinstalled a fresh image the other day). Should't that be enabled by default so people can stay up to date with security updates etc.?
