Oracle Solaris 10 9/10: Starting with this release, boot archive recovery on the SPARC platform is automatic.
To support auto-recovery of the boot archives on the x86 platform, a new auto-reboot-safe property has been added to the boot configuration service, svc:/system/boot-config:default. By default, the property's value is set to false to ensure that the system does not automatically reboot to an unknown boot device. If the system is configured to automatically point to the BIOS boot device and GRUB menu entry that Oracle Solaris 10 is installed on, you can set the property's value to true. Setting the value to true enables an automatic reboot of the system for the purpose of recovering an out-of-date boot archive.
For general information about this enhancement, see the boot(1M) man page.
