In one of the offsite reviews I read the author mentioned a Network Updater ISO, is that an option on the standard Disk 1? I haven't been able to find an ISO image that is as small at this reviewer was saying, like 1/10 the size of the standard installer.
Also, I *know* it's not recommended, but I've done it from FC1->2, 2->3 and 3->4 on several machines. Does anyone have any success stories of upgrading via yum?
