From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; Systemd specified that any /dev/pts/NNN device on which it is expected to spawn a agetty login, should be listed in the 'container_ttys' env variable. It should just contain the relative paths, eg 'pts/0' not '/dev/pts/0' and should be space separated. http://cgit.freedesktop.org/systemd/systemd/commit/?id=1d97ff7dd71902a560...
