SPARC: Installer Should Notify the User If diag-switch?=true on JumpStart Installation (6463765)

If the diag-switch of the PROM is set to true, the JumpStart installer issues a warning to change the default boot device even though the boot device was not changed during the install. The following error message is displayed:

WARNING: CHANGE DEFAULT BOOT DEVICE
If you want the system to always reboot Solaris from the boot
device that you've specified (c1t0d0s0), you must change the
system's default boot device using the eeprom(1M) command after
installing Solaris software.

Workaround: Set the diag-switch to false.
