actually, it's an option you choose in kernel configuration under Unix98
PTY support. from the blurb:
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 filesystem;
therefore, if you say Y here you should say Y to "/dev/pts filesystem for
Unix98 PTYs" as well.
