The init binary until now has been bind-mounted to /dev/init which breaks when bind-mounting to /dev. Instead mount the init to /run/podman-init. The reasoning for using /run is that it is already used for other runtime data such as secrets. Fixes: #14251 Signed-off-by: Valentin Rothberg <vrothberg@redhat.com>
