[Documentation] - Clarification regarding LOCAL_MIRROR

[OdinVex]

When using LOCAL_MIRROR=true, will this clone the entire repo or just the branch(es) used?

By the way, thank you very much for this project, I'm quite excited to test it out.

(I know that LOCAL_MIRROR is not yet working, I meant when it's finally used. ^_^)

Sorry - I don't know.

In my personal builds, before I got involved here as a project maintainer, I never used a local mirror, and I am very hazy about how it works and what it actually does.

Our monthly builds did use a local mirror, but when we had to restructure our main build script to fix #677, I originally left the 'USE_LOCAL_MIRROR' handling alone, hoping it would work in the new build structure, but it didn't. I did not have time then (and I don;t have time now) to debug and fix it, so I removed it, and we now make our builds without using a local mirror.

I would welcome a Pull Request which re-instated the ability to use a local mirror, but It's not something I have the time (or knowledge and expertise TBH) to work on myself. The project has more pressing problems which need to be fixed (see here

Agaim, sorry of this is not what you want to hear

LOCAL_MIRROR is now working. I still don't know the answer to your question, but I did a bit more digging when I was fixing #679

This post is the reference on how the --mirror flag should be used:

And this on how to use it with LineageOS

If those dont answer your question, you could maybe try it and see what happens 😄
