Verify: Install to BE

[beanpole135]

Verify that an install into a new Boot Environment works properly.

Good test system

• Previously-installed TrueOS 18.03 "desktop" edition

Seems to work in VirtualBox with one caveat:
The new BE is not automatically activated - the new BE needs to be activated either via the boot menu or with beadm from within the old BE.

Tested "staged" Trident-x64-20180905.iso , installed into 18.03 laptop with NO issues, except as mentioned above. Never gets activated. WiFi had to have script run and /etc/rc.conf edited to make saure entry has "SYNCDHCP" instead of "DHCP".

This has been tested and verified working.
The new boot environment has also setup for automatic activation.
