I'm not sure that we are talking about the same topic. I want to have acess to a bash shell with root rights. So i can run nmap on the local network e.g. without having my phone rooted (like what GrapheneOS endorses)
Anyways... I bought an usb-c flashdrive to make the VM persistent, but I can't make the partition visible to the app in the app settings, because it doesn't let me set a storage permission.
