I guessed it was a “once bitten twice shy” kind of thing. This is all a hobby to me so the cost-benefit, I think, is vastly different, nothing on my setup is critical. Keeping all those records and up to date on what version everything is on, and when updates are available and what those updates do and… sound like a whole lot of effort when currently my efforts can be better spent in other areas.

In my arrogance I just installed Watchtower, accepted it can all come crashing down. When that happens I’ll probably realise it’s not so much effort after all.

That said I’m currently learning, so if something is going to be breaking my stuff, it’s probably going to be me and not an update. Not to discredit your comment, it was informative and useful.
