I presume init(1M) will also need to be updated in the "6" section to
remove the x86-specific reference to fast reboot:
6
Stop the operating system and reboot to the state
defined by the initdefault entry in /etc/inittab.
On x86 systems, service svc:/system/boot-config:default
is enabled by default. When the
config/fastreboot_default property is set to true, init
6 will bypass the firmware.
Thanks,
Brian
