It would be great to showcase your great work done on Ubuntu Touch also on recent slimport-enabled devices that can better handle desktop apps and convergence.

Could you please update the porting guide with the steps required to provide the aarch64 rootfs?

This is related to issue 18 of Halium projectmanagement. I understand that this issue might not be on top of your priority list, but with this guide at hand, people could help and make ports for their own devices, without having to empirically recover the knowledge some of you may already have gained on this issue.
