Hello,
Thanks for all the clarification. I now find myself in need of doing this
again on another server running Jessie, and I just want to make sure I'm
clear on what the best procedure is. As I understand it, I should
copy /lib/systemd/system/[email protected] to
/etc/systemd/system/[email protected], then
edit [email protected] to include the following:
[Service]
ExecStart=
ExecStart=-/sbin/agetty -8 --noclear %I 9600 vt100
...
Is that correct?
Thanks!
Dave
