I rsynched fc10 today and burned boot.iso.
Diskboot.img mentioned in the README was missing.
I tried both gui and text install and did not see any way to specify an NFS install.
And of course since Fedora so wisely reformats the hard drive before doing anything, updating the drive is not an option.
I am hoping Fedora 10 will eventually be a smoothly installing and functioning system as is Fedora 8.
