The miniroot is a bootable root file system that includes the minimum Oracle Solaris OS software required to boot the server and configure the OS. The miniroot runs only during the installation process.
When the server boots the miniroot for the initial configuration, you might see the following messages in the system console:
Fatal server error: InitOutput: Error loading module for /dev/fb giving up. /usr/openwin/bin/xinit: Network is unreachable (errno 128): unable to connect to X server /usr/openwin/bin/xinit: No such process (errno 3): Server error.
The messages indicate that the Xsun server in the Oracle Solaris OS miniroot cannot find a supported driver for the AST graphics device in the service processor. These messages are legitimate, as the miniroot contains only the Xsun environment, and the AST frame buffer (astfb) is supported only in the Xorg environment. The Xorg environment is included in the installed system, so the graphics device might be used when running the installed Oracle Solaris OS.
Workaround: You can safely ignore this message.
