This is not the case for OmniOS.  For OmniOS root is a real user (with 
an empty password by default!) but /etc/default/login has this:

# If CONSOLE is set, root can only login on that device.
# If the specified device is /dev/console, then root can also log into
# any of the currently enabled /dev/vt/# virtual terminal devices.
# Comment this line out to allow remote login by root.
#
CONSOLE=/dev/console

so one can only login as root from the console.  If the current 
keyboard device is not associated with /dev/console or a /dev/vt/# 
device, then it would not be possible to login as root.
