So I just installed Fedora 14 in VirtualBox so I can switch it to Rawhide. Next, I do the first update after installing fedora-release-rawhide and I see probably the largest number of files to be updated that I've ever seen. It says, currently, 290/1669. We know that roughly half of this is "cleanup". That leaves approximately 835 files to be installed or updated! Holy cow! Lucky it's all happening pretty quickly or I'd need to go out to dinner or something and come back later
