<p class="MsoNormal">The ironic deploy templates feature wasn't designed to support forbidden traits - I don't think they were implemented at the time. The example use cases so far have involved encoding values into a trait name, e.g. CUSTOM_HYPERTHREADING_ON.
Forbidden traits could be made to work in this case, but it doesn't really extend to non Boolean things such as RAID levels.<o:p></o:p></p>
