+Unix98 PTY support
+CONFIG_UNIX98_PTYS
+  Linux traditionally uses BSD-like /dev/ptyxx and /dev/ttyxx names
+  for pseudo-ttys (PTYs).  This scheme has a number or problems.  The
+  GNU C library 2.1 and later, however, supports the Unix98 naming
+  standard, using a cloning device /dev/ptmx and numbered devices in a
+  subdirectory /dev/pts/xxx.  The device nodes in /dev/pts can be
+  automatically generated by the devpts virtual filesystem.

+  Say Y here if you are uncertain, unless you are very short on memory.

+Maximum number of Unix98 PTYs in use (0-2048)
+CONFIG_UNIX98_PTY_COUNT
+  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,
+  however, server machines which support incoming telnet/rlogin/ssh
+  connections may want to increase this.  When not in use, each
+  additional set of 256 PTYs occupy approximately 8K of kernel memory
+  on 32-bit architectures.
