Subject: [PATCH 2/5] tty/vt: move files to drivers/tty/vt/
The virtual terminal is a very special tty driver, so
it deserves its own directory.

- ---help---
- If you say Y here, you will get support for terminal devices with
- display and keyboard devices. These are called "virtual" because you
- can run several virtual terminals (also called virtual consoles) on
- one physical terminal. This is rather useful, for example one
- virtual terminal can collect system messages and warnings, another
- one can be used for a text-mode user session, and a third could run
- an X session, all in parallel. Switching between virtual terminals
- is done with certain key combinations, usually Alt-<function key>.
-
- The setterm command ("man setterm") can be used to change the
- properties (such as colors or beeping) of a virtual terminal. The
- man page console_codes(4) ("man console_codes") contains the special
- character sequences that can be used to change those properties
- directly. The fonts used on virtual terminals can be changed with
- the setfont ("man setfont") command and the key bindings are defined
- with the loadkeys ("man loadkeys") command.
-
- You need at least one virtual terminal device in order to make use
- of your keyboard and monitor. Therefore, only people configuring an
- embedded system would want to say N here in order to save some
- memory; the only way to log into such a system is then via a serial
- or network connection.
-
- If unsure, say Y, or else you won't be able to do much with your new
- shiny Linux system :-)

- on virtual consoles.
-
-config VT_CONSOLE
- bool "Support for console on virtual terminal" if EMBEDDED
- depends on VT
- default y
- ---help---
- The system console is the device which receives all kernel messages
- and warnings and which allows logins in single user mode. If you
- answer Y here, a virtual terminal (the device used to interact with
- a physical terminal) can be used as system console. This is the most
- common mode of operations, so you should say Y here unless you want
- the kernel messages be output only to a serial port (in which case
- you should say Y to "Console on serial port", below).
-
- If you do say Y here, by default the currently visible virtual
- terminal (/dev/tty0) will be used as system console. You can change
- that with a kernel command line option such as "console=tty3" which
- would use the third virtual terminal as system console. (Try "man
- bootparam" or see the documentation of your boot loader (lilo or
- loadlin) about how to pass options to the kernel at boot time.)
-
- If unsure, say Y.

-config VT_HW_CONSOLE_BINDING
- bool "Support for binding and unbinding console drivers"

- ---help---
- The virtual terminal is the device that interacts with the physical
- terminal through console drivers. On these systems, at least one
- console driver is loaded. In other configurations, additional console
- drivers may be enabled, such as the framebuffer console. If more than
- 1 console driver is enabled, setting this to 'y' will allow you to
- select the console driver that will serve as the backend for the
- virtual terminals.
