I'm currently going through Linux from Scratch to build a distro. My reason for doing so is curiosity more than anything. I've not had any issues and learning a lot.
But, what I'd like to know is without Linux from Scratch are there any other ways to build a distro without using another distro as a base?
By this I mean if LFS wasn't around how else would you build a distro from scratch? I'm guessing Gentoo was created using a primitive approach.
Thanks for any advice.
