Any developments at all?

this is most recent info regarding installing waydroid on danctnix (arch):

https://fosstodon.org/@xaviers/106936888809418637

Installation instructions:
sudo pacman -S waydroid-image
sudo waydroid init -f
sudo systemctl enable waydroid-container --now

and this reddit post has info on installing it to images not using boot/boot.txt, though the pkg link is dead, so the package would need to be grabbed from another repo.

With a little bit of luck, the Wayback Machine might be able to pull the package out of their archive (http://archive.org/web)

it may not be necessary, just found the new waydroid-image package in the manjaro community repo, so i could be grabbed from there too

EDIT: waydroid command not found gets reported on my tab manjaro install (havent tried pbp yet) and systemctl cannot find the service file for waydroid-container.
