Perhaps I missed something in this discussion, but if anaconda can (almost 
always) setup grub correctly once, why can't we have an application, perhaps 
based on the same code, to redo the process?  If I understand, you are saying 
the job is difficult, but it's already been solved once.  Is this not 
correct?
