  config STDERR_CONSOLE
  	bool "stderr console"
  	default y
  	help
  	  console driver which dumps all printk messages to stderr.
  
  config SSL
  	bool "Virtual serial line"
  	help
            The User-Mode Linux environment allows you to create virtual serial
            lines on the UML that are usually made to show up on the host as
            ttys or ptys.
  
            See <http://user-mode-linux.sourceforge.net/old/input.html> for more
            information and command line examples of how to use this facility.
  
            Unless you have a specific reason for disabling this, say Y.
  
  config NULL_CHAN
  	bool "null channel support"
  	help
            This option enables support for attaching UML consoles and serial
            lines to a device similar to /dev/null.  Data written to it disappears
            and there is never any data to be read.
  
  config PORT_CHAN
  	bool "port channel support"
  	help
            This option enables support for attaching UML consoles and serial
            lines to host portals.  They may be accessed with 'telnet <host>
            <port number>'.  Any number of consoles and serial lines may be
            attached to a single portal, although what UML device you get when
            you telnet to that portal will be unpredictable.
            It is safe to say 'Y' here.
  
  config PTY_CHAN
  	bool "pty channel support"
  	help
            This option enables support for attaching UML consoles and serial
            lines to host pseudo-terminals.  Access to both traditional
            pseudo-terminals (/dev/pty*) and pts pseudo-terminals are controlled
            with this option.  The assignment of UML devices to host devices
            will be announced in the kernel message log.
            It is safe to say 'Y' here.
  
  config TTY_CHAN
  	bool "tty channel support"
  	help
            This option enables support for attaching UML consoles and serial
            lines to host terminals.  Access to both virtual consoles
            (/dev/tty*) and the slave side of pseudo-terminals (/dev/ttyp* and
            /dev/pts/*) are controlled by this option.
            It is safe to say 'Y' here.
  
  config XTERM_CHAN
  	bool "xterm channel support"
  	help
            This option enables support for attaching UML consoles and serial
            lines to xterms.  Each UML device so assigned will be brought up in
            its own xterm.
            It is safe to say 'Y' here.
  
  config NOCONFIG_CHAN
  	bool
  	default !(XTERM_CHAN && TTY_CHAN && PTY_CHAN && PORT_CHAN && NULL_CHAN)
  
  config CON_ZERO_CHAN
  	string "Default main console channel initialization"
  	default "fd:0,fd:1"
  	help
            This is the string describing the channel to which the main console
            will be attached by default.  This value can be overridden from the
            command line.  The default value is "fd:0,fd:1", which attaches the
            main console to stdin and stdout.
            It is safe to leave this unchanged.
  
  config CON_CHAN
  	string "Default console channel initialization"
  	default "xterm"
  	help
            This is the string describing the channel to which all consoles
            except the main console will be attached by default.  This value can
            be overridden from the command line.  The default value is "xterm",
            which brings them up in xterms.
            It is safe to leave this unchanged, although you may wish to change
            this if you expect the UML that you build to be run in environments
            which don't have X or xterm available.
  
  config SSL_CHAN
  	string "Default serial line channel initialization"
  	default "pty"
  	help
            This is the string describing the channel to which the serial lines
            will be attached by default.  This value can be overridden from the
            command line.  The default value is "pty", which attaches them to
            traditional pseudo-terminals.
            It is safe to leave this unchanged, although you may wish to change
            this if you expect the UML that you build to be run in environments
            which don't have a set of /dev/pty* devices.
  
  config UML_SOUND
  	tristate "Sound support"
  	help
            This option enables UML sound support.  If enabled, it will pull in
            soundcore and the UML hostaudio relay, which acts as a intermediary
            between the host's dsp and mixer devices and the UML sound system.
            It is safe to say 'Y' here.
