Re: I've opted out of 18.04
If you know exactly what you want (and don't want) then Gentoo is likely a good home for you. It's the only workable way to get pretty much exactly the distro you want, whatever that may be. There are other options that get you kind of close-ish to what you want; and some that get you exactly what you want but are a nightmare to maintain long-term.
I've personally found it just a bit too much hard work to maintain on servers but on my desktop I couldn't live with anything else.
