I'm creating my own distro. I'm pretty much learning everything on the fly and had a question. Mint is based on Ubuntu which is based on Debian. Am I correct in assuming that, in this case, the mint sources take precedence and default to the Ubuntu packages when no mint alternative is available and same situation Ubuntu to Debian.
Does every distro compile everything themselves? That doesn't make sense to me.
The purpose of the question is, in mint when using synaptic to view sources list (or at the file) as I recall it is all Linux mint named, as Ubuntu is all named Ubuntu (like, Ubuntu multiverse) how would I do the same, rename everything to my distro name and such? What all is involved? And answers would be greatly appreciated.
