I personally don’t enable automated upgrades anywhere, but I’m 25yrs into sysadmin and I have a pathological aversion to services being down.

I use some automation with ansible, but I like manual triggering so that a problem can manifest when I want it to (like a change window) and I can respond appropriately.

I also would include steps to back up the ssh public keys or have an alternate console available.

But as someone else mentioned, these seem to be someone’s step guide to installs.
