NAME

zcons — Zone console device driver

DESCRIPTION

The zcons character driver exports the console for system zones. The driver is fundamentally similar to a pseudo-terminal device, and is thus comprised of two sides:

• a manager device, which applications in the global zone can open for communication
• a subsidiary device, which processes in the non-global zone can write to, to communicate with global zone management applications

Applications must not depend on the location of /dev or /devices entries exposed by zcons in the global zone. Inside a non-global zone, the zcons subsidiary device is fronted by /dev/console and other console-related symbolic links, which are used by applications that expect to write to the system console.

The zcons driver is not a Committed interface, and may change at any time.
