	Finally got around to this today. It worked; many many thanks! I 
had to mess around a while in some places -- perhaps because I've only

	The machine in need had only one hard drive; so I skipped the

	How do you get into anaconda -- is there a way without a rescue

	Hadn't ever heard of dailypackage; many thanks! Heavy stuff, at
