Oh.  Boy I feel stupid.  So UCarp is REALLY just the Carp, I feel  
like an idiot, I thought UCarp brought up the ipalias all by itself.   
(*doh!*)  But it ONLY does the Carp.  Boy I feel stupid.

So, I'll do it again when I'm back touching that machine again,  
adding the appropriate ifconfig alias statements to the up and down  
scripts.
