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:

+o a manager device, which applications in the global zone can open for
communication

+o 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.
