Closed issue by WilliamBehrens on void-packages repository

https://github.com/void-linux/void-packages/issues/34205

Description:
I'm wanting to create my own custom mirror for void packages as I want to add a custom base-system and kernel but I don't think it would really be something to commit into the main void-packages repo. Something that I can't seem to find a direct answer too strangely is if it's possible to have multiple packages mirrors at once. So if I have my own custom repo hosted on my network and still be able to install packages from the main void repo. Another thing that isn't really documented if multiple repos is a thing is if each mirror has to host ALL of the packages in the main void repo or even if they just require the dependancies of the custom packages(like if I have a custom version of glew do I need to host my own version of glu or can glu be pulled from the main mirror to compile glew). I was hoping to be able to remove all the packages I'm not using to reduce the storage requirement of the mirror basically.
