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!

14 | ---help--- | ||
15 | A pseudo terminal (PTY) is a software device consisting of two | ||
16 | halves: a master and a slave. The slave device behaves identical to | ||
17 | a physical terminal; the master device is used by a process to | ||
18 | read data from and write data to the slave, thereby emulating a | ||
19 | terminal. Typical programs for the master side are telnet servers | ||
20 | and xterms. | ||
21 | |||
22 | Linux has traditionally used the BSD-like names /dev/ptyxx for | ||
23 | masters and /dev/ttyxx for slaves of pseudo terminals. This scheme | ||
24 | has a number of problems. The GNU C library glibc 2.1 and later, | ||
25 | however, supports the Unix98 naming standard: in order to acquire a | ||
26 | pseudo terminal, a process opens /dev/ptmx; the number of the pseudo | ||
27 | terminal is then made available to the process and the pseudo | ||
28 | terminal slave can be accessed as /dev/pts/<number>. What was | ||
29 | traditionally /dev/ttyp2 will then be /dev/pts/2, for example. | ||
30 | |||
31 | The entries in /dev/pts/ are created on the fly by a virtual | ||
32 | file system; therefore, if you say Y here you should say Y to | ||
33 | "/dev/pts file system for Unix98 PTYs" as well. | ||
34 | |||
35 | If you want to say Y here, you need to have the C library glibc 2.1 | ||
36 | or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*"). | ||
37 | Read the instructions in <file:Documentation/Changes> pertaining to | ||
38 | pseudo terminals. It's safe to say N. | ||

44 | help | ||
45 | The maximum number of Unix98 PTYs that can be used at any one time. | ||
46 | The default is 256, and should be enough for desktop systems. Server | ||
47 | machines which support incoming telnet/rlogin/ssh connections and/or | ||
48 | serve several X terminals may want to increase this: every incoming | ||
49 | connection and every xterm uses up one PTY. | ||
50 | |||
51 | When not in use, each additional set of 256 PTYs occupy | ||
52 | approximately 8 KB of kernel memory on 32-bit architectures. | ||
