Now mmdebstrap can create a dawn chroot from debian sid (for example to build a package targeting dawn) $ sudo mmdebstrap --arch arm64 dawn dawn http://repo.pureos.net/pureos
This was not working with crimson when I tried last time. I want to try switching to pipewire Echo cancellation with pipewire (for dawn) - need testers and first step would be rebuilding librem5-base package to allow using pipewire instead of pulseaudio.
