omg me too... a much nerdier friend of mine told me to install Gentoo on my first custom build back in the early aughts. printed out the guide and spent over a week 24/7 compiling everything with an athlon 64 3500+... and had never used Linux before this... good times, man.
There's a lot to love about Gentoo. I miss it dearly, but I've been using NixOS lately and have been very happy with it too. It's just quite a lot easier to maintain and the model for packages makes it a lot easier to set up binary caches and stuff... Still, there's something very cozy about our dear portage :).
