Which two options are characteristics of a fast reboot?
A.
A fast reboot bypasses grub.
B.
A fast reboot cannot be used after a system panic on the x86 platform.
C.
A fast reboot can only be executed on the SPARC platform when the config/fastreboot_default property for
the svc:/system/boot-config:default service is set to true.
D.
A fast reboot uses an in-kernel boot loader to load the kernel into memory.
E.
A fast reboot is the default on all platforms.
Explanation:
C: To change the default behavior of the Fast Reboot feature on the SPARC platform, so that a fast reboot is
automatically performed when the system reboots, see below.
The following example shows how to set the property’s value to true on the SPARC platform, so that a fast
reboot is initiated by default:
# svccfg -s “system/boot-config:default” setprop config/fastreboot_default=true
# svcadm refresh svc:/system/boot-config:default
D: Fast Reboot implements an in-kernel boot loader that loads the kernel into memory and then switches to that
kernel.
The firmware and boot loader processes are bypassed, which enables the system to reboot within seconds.
The Fast Reboot feature is managed by SMF and implemented through a boot configuration service, svc:/
system/boot-config. The boot-config service provides a means for setting or changing the default boot
configuration parameters. When the config/fastreboot_default property is set to true, the system performs a fast
reboot automatically, without the need to use the reboot -f command. This property’s value is set to true on the
x86 platform. For task-related information, including how to change the default behavior of Fast Reboot on the
SPARC platform, see Accelerating the Reboot Process on an x86 Based System.
Note: One new feature, called Fast Reboot, will allow the system to boot up without doing the routine set of
hardware checks, a move that can make system boot times up to two-and-a-half times faster, Oracle claimed.
This feature can be handy in that an administrator applying a patch or software update across thousands of
Solaris deployments can reboot them all the more quickly.
