Adding that documentation is likely confusing unless it's a separate section in UPDATING, so if you want to write a new section on how to do that, and when you can and can't use it, we can include that in UPDATING.... Also boot environments in 11.1R were somewhat tricky and difficult to arrange, absent tools not present in base at the time, which is where I was coming from. Warner
