The entries in /etc/ttys control which devices have gettys
running on them.  It does nothing to control where the kernel
emits messages.

No.  NetBSD (and traditional UNIX in general), has only *one*
console device.  aka, one device where kernel messages are emitted.

xconsole(1) uses ioctl to set the flag TIOCCONS, which,
according to the tty(4) manual page:

     TIOCCONS int *on
		 If on points to a non-zero integer, redirect kernel
		 console output (kernel printf's) to this terminal.
		 If on points to a zero integer, redirect kernel
		 console output back to the normal console.  This
		 is usually used on workstations to redirect kernel
		 messages to a particular window.

Kernel messages can only go to one terminal.  (and /dev/klog,
which syslogd(8) uses to pick them up.) xconsole says the pty it
has opened is that terminal.

"gettings"? My fingers must be overriding my brain while typing.  :D
I meant "gettys".
