Perhaps you remember I am occassionally running #emacs on android with speechd-el and espeak-ng providing speech output. Up to now I was using termux for doing that.
Now I'm trying to get it to run on a pixel 9A with @GrapheneOS and the terminal app with #avf under the hood.

The thing is I'd like to get more up to date packages in that virtualized environment running on my phone. I'd prefer #ArchLinuxARM based image or #Debian testing. Upgrading it by following debian's instructions I am getting broken image. I have found there's nixos-avf however I can't find more.

Do you know if someone has succeeded building other images that might help me to get to my goal easier?
