I agree that this is the best solution.  Fix dracut to only activate 
and mount /.  I found these bugs closed as NOTABUG:

https://bugzilla.redhat.com/show_bug.cgi?id=512620
https://bugzilla.redhat.com/show_bug.cgi?id=524366

and this is the one I had just opened:

https://bugzilla.redhat.com/show_bug.cgi?id=525877

so if this is "working as intended" is there any chance of changing 
the default behavior to work as expected above?
