In your case, ExecStart is a setting which can not be specified more then once. So you need to "clear" it first. The following should do the trick: [Service] ExecStart= ExecStart=-/sbin/agetty -8 --noclear %I 38400 ibm3151 The "ExecStart=" resets the existing setting. See also man 5 systemd.unit , "Example 2.

See below for an example. Cheers, Michael -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
