54.Pp
55Upon successful completion, the system will be ready to boot into the new boot
56environment.
57Upon failure, the target boot environment will be destroyed.
58In all cases, the running system is left untouched
59and a reboot into a partially updated system
60(due to install or hardware failure) cannot happen.
61Additionally, the full installation process requires
62only one reboot as it is performed
63in a new boot environment.
