(maybe not what you were asking) But for beginners there are some pretty nice LineageOs build guides floating around: For specific pieces of hardware: https://wiki.lineageos.org/build_guides.html https://wiki.lineageos.org/build_guides.html Generic instructions: https://forum.xda-developers.com/chef-central/android/how-to-build-lineageos-14-1-t3551484 https://forum.xda-developers.com/chef-central/android/how-to... As far as changing the certs, I know offhand to do it with a couple random linux distro's but i'm not 100% sure for android, you might just try searching the repo for the default certs then looking at how they are built into the image and tweaking that.
