To support Fast Reboot, the reboot command has been modified to include two new options:
Initiates the fast reboot process, when used with the reboot command.
Initiates a fast reboot to an alternate boot environment (BE), when used in conjunction with the -f option,
The -e option cannot be used to fast reboot to an alternate BE in the OpenSolaris 2008.11 release. For instructions on initiating a fast reboot to an alternate BE in this release, see x86: Initiating a Fast Reboot to an Alternate Boot Environment in the OpenSolaris 2008.11 OS.
