We could just extend the error message to explain the intent.  It could 
also explain that --no-bootstrap-sync is useful for trying out bootstrap 
modifications.  For longer experiments, it could suggest setting 
bootstrap_sync=false in bootstrap.conf.  Would that make it better?

We would likely overlook the note if it doesn't fail immediately 
afterward.
