@luana@wetdry.world It will fully support using other operating systems including users making their own builds of GrapheneOS. It's part of our hardware requirements. We'll likely be able to make hardened builds of firmware and drivers which can be released in an official way for easy builds without needing to extract anything from the GrapheneOS or Motorola OS factory images.
Yep, if only these damn manufacturers would actually give a bit of care and cater to our damned needs.
