Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+ ---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 :-)
+
+config VT_CONSOLE
+ bool
+ 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.)

+ than one CPU, say Y.
+
+ If you say N here, the kernel will run on single and multiprocessor
+ machines, but will use only one CPU of a multiprocessor machine. If
+ you say Y here, the kernel will run on many, but not all,

+ will run faster if you say N here.

+ SPARC is a family of RISC microprocessors designed and marketed by
+ Sun Microsystems, incorporated. They are very widely found in Sun
+ workstations and clones. This port covers the original 32-bit SPARC;

+ Say Y here if you want to attach PCMCIA- or PC-cards to your Linux

+ actually two varieties of these cards: the older 16 bit PCMCIA cards
+ and the newer 32 bit CardBus cards. If you want to use CardBus
+ cards, you need to say Y here and also to "CardBus support" below.
+
+ To use your PC-cards, you will need supporting software from David
+ Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
+ for location). Please also read the PCMCIA-HOWTO, available from

+ ---help---
+ If you say Y here, it will be possible to use a serial port as the

+ mode). This could be useful if some terminal or printer is connected
+ to that serial port.
+
+ Even if you say Y here, the currently visible virtual console
+ (/dev/tty0) will still be used as the system console by default, but
+ you can alter that using a kernel command line option such as
+ "console=ttyS1". (Try "man bootparam" or see the documentation of
+ your boot loader (silo) about how to pass options to the kernel at
+ boot time.)
+
+ If you don't have a graphics card installed and you say Y here, the
+ kernel will automatically use the first serial line, /dev/ttyS0, as
+ system console.

+ printer has 9 or 25 holes ["female"], then it's serial), say Y.
+ Also read the Printing-HOWTO, available from
+ <http://www.tldp.org/docs.html#howto>.
+
+ It is possible to share one parallel port among several devices
+ (e.g. printer and ZIP drive) and it is safe to compile the
+ corresponding drivers into the kernel. If you want to compile this
+ driver as a module however, choose M here and read
+ <file:Documentation/parport.txt>. The module will be called lp.
+
+ If you have several parallel ports, you can specify which ports to
+ use with the "lp" kernel command line option. (Try "man bootparam"
+ or see the documentation of your boot loader (silo) about how to pass
+ options to the kernel at boot time.) The syntax of the "lp" command
+ line option can be found in <file:drivers/char/lp.c>.
+
+ If you have more than 8 printers, you need to increase the LP_NO
+ macro in lp.c and the PARPORT_MAX macro in parport.h.

+
+config UNIX98_PTYS
+ bool "Unix98 PTY support"
+ ---help---
+ A pseudo terminal (PTY) is a software device consisting of two
+ halves: a master and a slave. The slave device behaves identical to
+ a physical terminal; the master device is used by a process to
+ read data from and write data to the slave, thereby emulating a
+ terminal. Typical programs for the master side are telnet servers
+ and xterms.
+
+ Linux has traditionally used the BSD-like names /dev/ptyxx for
+ masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
+ has a number of problems. The GNU C library glibc 2.1 and later,
+ however, supports the Unix98 naming standard: in order to acquire a
+ pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
+ terminal is then made available to the process and the pseudo
+ terminal slave can be accessed as /dev/pts/<number>. What was
+ traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
+
+ The entries in /dev/pts/ are created on the fly by a virtual
+ file system; therefore, if you say Y here you should say Y to
+ "/dev/pts file system for Unix98 PTYs" as well.
+
+ If you want to say Y here, you need to have the C library glibc 2.1
+ or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
+ Read the instructions in <file:Documentation/Changes> pertaining to
+ pseudo terminals. It's safe to say N.
+
+config UNIX98_PTY_COUNT

+ default "256"
+ help
+ The maximum number of Unix98 PTYs that can be used at any one time.
+ The default is 256, and should be enough for desktop systems. Server
+ machines which support incoming telnet/rlogin/ssh connections and/or
+ serve several X terminals may want to increase this: every incoming
+ connection and every xterm uses up one PTY.
+
+ When not in use, each additional set of 256 PTYs occupy
+ approximately 8 KB of kernel memory on 32-bit architectures.
