Her name is Oreo#

I am at a point somewhere along the way of a long yak-shaving journey ("I wonder if the MSM8953 SoC supports ANT+ in hardare and it just needs enabling in the Android software?") which involves rebuilding Android for my phone. There seem to be very few ROMs for the Moto G5 Plus ("potter") that are still being maintained, and even fewer of them that have build instructions that (a) work as described; (b) comprise fewer than 30 manual steps. Do Android ROM developers not do CI builds? If this was all GPL I could make a strong case it's in breach. ("The source code for a work means the preferred form of the work for making modifications to it [...] all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable."). Yes, I know, volunteers, spare time, teeth of gift horses, etc etc. End rant

Anyway, so far I am doing the following and it has not yet blown up

1) using the docker image from LineageOS for Microg

2) invoking it as follows

docker run \
    -e "BRANCH_NAME=lineage-15.1" \
    -e "DEVICE_LIST=potter" \
    -e "SIGN_BUILDS=false" \
    -e "SIGNATURE_SPOOFING=restricted" \
    -e "INCLUDE_PROPRIETARY=false" \
    -e "WITH_SU=true" \
    -e "CUSTOM_PACKAGES=GmsCore GsfProxy FakeStore MozillaNlpBackend NominatimNlpBackend com.google.android.maps.jar FDroid FDroidPrivilegedExtension " \
    -v "/$HOME/src/android/l4mg/lineage:/srv/src" \
    -v "/$HOME/src/android/l4mg/zips:/srv/zips" \
    -v "/$HOME/src/android/l4mg/logs:/srv/logs" \
    -v "/$HOME/src/android/l4mg/cache:/srv/ccache" \
    -v "/$HOME/src/android/l4mg/keys:/srv/keys" \
    -v "/$HOME/src/android/l4mg/manifests:/srv/local_manifests" \
    lineageos4microg/docker-lineage-cicd

3) with this manifest in $HOME/src/android/l4mg/manifests/roomservice.xml

<?xml version="1.0" encoding="UTF-8"?>
<manifest>
	<project name="LineageOS/android_external_bson" path="external/bson" remote="github" revision="cm-14.1" />
	<project name="LineageOS/android_device_qcom_common" path="device/qcom/common" remote="github" revision="lineage-15.1" />
	<project name="LineageOS/android_packages_resources_devicesettings" path="packages/resources/devicesettings" remote="github" revision="staging/lineage-15.1" />
	<project name="boulzordev/android_device_motorola_potter" path="device/motorola/potter" remote="github" revision="lineage-15.1-64" />
	<project name="boulzordev/android_vendor_motorola_potter" path="vendor/motorola/potter" remote="github" revision="lineage-15.1-64" />
	<project name="boulzordev/android_kernel_motorola_msm8953" path="kernel/motorola/msm8953" remote="github" revision="lineage-15.1-64" />
</manifest>

Worthy of note:

I found the manifest on the Interwebz by use of a search engine. I had to edit the revision attribute of android_device_qcom_common from staging/lineage-15.1 to lineage-15.1
because I have a (presumed working) example manifest for 15.1 I am not attempting to build any newer version. One change at a time, hey
in my limited understanding, the manifest tells the build system where to find Moto proprietary files, and the INCLUDE_PROPRIETARY=false build argument tells the L4microg build scripting not to try and download them from "TheMuppets". This is important because the muppets don't have them for my device.
getting F-droid and Microg baked in is probably no bad thing

As I write this, it has been building for ~ 30 minutes and not fallen over yet, so things are looking vaguely promising

[  8% 8343/95970] target thumb C++: libv8src_32 <= external/v8/src/builtins/builtins-constructor.cc

Apparently it's done 8% of something

It works! It built a buch of stuff in zips/potter/ including the file lineage-15.1-20210212-UNOFFICIAL-potter.zip which I installed from Recovery using the instructions at https://wiki.lineageos.org/devices/peregrine/install Yes, that's not the same phone, but it's close enough to use the same procedure
