Build single hybrid CD/USB ISO image
In order to release FreeNAS 11.2 beta 1 by 06-25-18 it was decided by release engineering we need a single image again. We would like to make the BSD loader the default for BETA1, and simple remove the NOGRUB tag. We will need the fix cherry picked into the 11.2-stable branch of freenas/build in order for this to work for us.
- Needs Doc changed from Yes to No
Reviewed "Preparing the Media" section in both master and angulargui branches of the Guide. I don't see any remaining references to a split .iso/.img setup for the FreeNAS install files. Everything appears to be consistent.
