Tl;dr: Automatic updates on my home server caused 8 hours of downtime of all of renn.es’ docker services including email and public websites
Blind automatic upgrades are a bad idea even for casual home users. You could run into a Linus Tech Tips “do as I say” scenario where it uninstalls half your system due to a dependency issue. Or it could accidentally uninstall part of your system that you don’t notice.
I’m not sure how stable Gentoo’s default branch is but I know that daily upgrades on Arch Linux is close to suicide - you have a higher chance of installing a buggy package before it’s fixed if you install every package version as it comes in.
I’m surprised this strategy was approved for a public server - it’s playing with a loaded revolver and it looks like you were finally shot.

Right, it was clearly LTT’s fault for not reading, but automatic upgrades are the same thing as not reading. I’ve been using Linux for a very long time now, and I’ve seen Apt try to do some very stupid things before. Maybe it’s better nowadays but I don’t know if I’ll ever shake the gut instinct to not allow Apt to do whatever it thinks is right.
