My peace of mind comes from my self hosting in 2025 looking the same as my self-hosting in 2005 (except a move to systemd). I haven't even re-installed my workstation OS since 2006 or so.

I'm just a boomer (technically a millennial) who sticks to Arch Linux even when it comes to servers, I have zero friction, really. I have no issues self-hosting whatever me or a client requires, keeping it minimal and functional.
I self-host like it is 2000 (apart from a couple of some more modern stuff, if you could consider systemd and certbot, etc. modern). :D
