From d9ff0fd15da268fae9744a60522ecdf94744b74a Mon Sep 17 00:00:00 2001 From: Ashley Cui Date: Fri, 24 Jun 2022 10:22:25 -0400 Subject: Only allow Rootless runs of Podman Machine Podman Machine crashes if run as root. When creating the machine, we write the ignition so that the UID of the core user matches the UID of the user on the host. We by default, create the root user on the machine with UID 0. If the user on the host is root, the core UID and the Root UID collide, causing a the VM not to boot.
