Removing Gnome on OpenSolaris
The LiveCD does not allow the user to customize what packages to install, similar to what Solaris 10 and other server operating system do. There is no documented way of removing large package sets like Gnome and Xorg. For a headless server setup you can remove unnecessary desktop applications with the following command:
pkg uninstall -vr \`pkg list | egrep '(aac|acc|atheros|audio|avahi|compiz|evolution|firefox|flac|gamin|gnome|ipp|ipw|iwi|iwk|musicbrainz|ogg|pkg-gui|print|thunderbird|tnetd|wlan|wlan|wpa|wpi|xcursor|xorg|xscreensaver)' | awk '{print $1}'\`
