Happens after mounting NFS, or finishing downloading HTTP stage2.
Comment 2 Chris Lumens 2007-10-11 15:54:00 EDT

transferring http://something/somewhere to a fd

Hey, it's the updates image.

transferring http://172.31.4.2/fedora/updates.img to a fd
Comment 4 Chris Lumens 2007-10-12 16:05:56 EDT
This will be fixed in the next build of anaconda.
