Strictly speaking "console" should be _removed_ from /etc/ttys. It is
(now) always the wrong device to run getty on. A "constty" entry is the
only correct way to properly access the system console TTY device.
It still has meaning for single user mode. See init(8):
If the `console' entry in the ttys(5) file is marked ``insecure'', then
init will require that the superuser password be entered before the sys-
tem will start a single-user shell. The password check is skipped if the
`console' is marked as ``secure''.
So you can have something like this in /etc/ttys :
console "/usr/libexec/getty Pc" vt100 off insecure
ttyE0 "/usr/libexec/getty Pc" vt220 on secure
