This repository contains manifests to setup a Android Mirror, AOSP & LineageOS.

The main goal of the project is to save disk space, and cut down on duplicate network transfers by restricting them to a single point (the mirror)

The local_manifests directory contains local manifests I have been using, since basically forever.

Current Setup:

URL=https://github.com/LineageOS/mirror

Mirrors

mirror/aosp

repo init -u $URL -m aosp-minimal.xml --mirror

  • Also contains all the local manifests under local_manifests/mirror/aosp

mirror/cm

repo init -u $URL -m lineage-minimal.xml --mirror

  • Also contains all the local manifests under local_manifests/mirror/cm
  • Another thing I do is symlink {device,external,kernel,platform} from the AOSP mirror here, so that it gets picked up when initing Lineage and setting this as --reference

Working directories

lineage/16.0

repo init -u path/to/mirror/cm/chirayudesai/potential-octo-dangerzone.git -b lineage/lineage-16.0 --reference=path/to/mirror/cm

  • I use a custom manifest here with one change, fetch AOSP from '..' instead of the actual URL. This means that this repo does not actually touch the network at all.
  • 194M .repo

aosp/9.0

repo init -u path/to/mirror/aosp/platform/manifest.git --reference=path/to/mirror/aosp

  • Nothing too fancy here, just a sync from mirror + reference to mirror.
  • 183M .repo

Scripts

bin/repo2

Wrapper to sync a repository in the mirror first Not fully complete, but does the job for most of the repos.

bin/aosp-mirror-to-cm.sh

Something crazy I did while setting up these mirrors. Refer to AOSP objects in the forked CM repos, to save even more space. E.g. Lineage forks aosp/platform/external/foo as LineageOS/android_external_foo This script you setup the Lineage repo to refer to objects from the AOSP mirror.
