pixelmod

Pixelmod is a small AOSP modification for the Pixel 5 (redfin) devices, that excludes some of the default apps and includes some other prebuilts apps like F-Droid. It's not an official ROM or anything, it's just my personal modification to make the build easier for me.

Modifications

Remove Browser2 (WebViewShell)
Remove Camera2
Remove QuickSearchBox
Add F-Droid Prebuilt APK

Build AOSP (pixelmod)

sed -i "s/lxc.net.0.type = empty/lxc.net.0.type = none/g" /var/lib/lxc/aosp/config

lxc-start aosp
lxc-attach aosp

echo 'echo "nameserver 8.8.8.8" > /etc/resolv.conf' >> /root/.bashrc && exit
lxc-attach aosp
