After upgrade to "systemd" my /dev/ttyS0 shows up as: root:dialout ownership and permission 600
When I change as root manually to: chown uucp:dialout /dev/ttyS0 chmod 666 /dev/ttyS0 after restart it goes back to previous setting: root:dialout 600 How to change it? My VituralBox complain and will not start with owner: root:dialout /dev/ttyS0 -- Joseph
