"or any AppVM terminal" scratch those 4 words out, I don't know why I wrote these, when its neither feasible nor secure to do it inside an AppVM <.< but it of course only works in dom0 terminal from a technical/practical perspective too. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
