Description of problem: I keep a copy of rawhide on disc. To test the rc trees, I figured I'd save time and bandwidth by just syncing it to the rc1 tree, then booting off a copy of the rc rescue cd to do a local disk install... But NOOOOO, it had to have copies of the ISO images on disc. A tree with all the packages wasn't good enough for it. Ok, whatever. So I try an http install, and point it to the iso/ directory on testing.fedora, since it just said it wanted iso images... But NOOOOO, now it wants a tree with the packages, instead of iso images! I did switch it to the os/ directory and the http install then worked fine. But in case it's not blatantly obvious where I'm headed here, I think either format of the data (isos or package tree) should work with any retrieval method the installer supports. Version-Release number of selected component (if applicable): anaconda-10.1.0.0-1 as of this writing.
ISOs are preferred in almost all cases, but aren't usable for HTTP/FTP installs as I can't loopback mount an ISO via FTP/HTTP.
