When running installadm create-client,
the client grub.conf.01macaddress file is
generated from the following file:
/var/ai/service/"service- name"/menu.conf
to change the menu-order from text-installer to
automated-installer change the followin entry:
[meta]
order = SolarisNetBootInstance|0, SolarisNetBootInstance|1
to
[meta]
order = SolarisNetBootInstance|1, SolarisNetBootInstance|0
Now the first entry will be the automated installer.
