In NTH review discussion of https://bugzilla.redhat.com/show_bug.cgi?id=871554 , Jesse explained that he is tracking several issues related to NFS ISO installations. It was agreed to split these up as separate, specific bug reports. Therefore this bug is for the following problem: according to Jesse, in current anaconda for F18, you cannot successfully do an NFS ISO install via the interactive Installation Source spoke in the graphical installer. If you set the source to be an NFS server path pointing to an appropriate Fedora ISO file, or a directory containing a single appropriate Fedora ISO file, this ought to work. However, at present, it does not. (I have not confirmed this personally). Proposing as NTH at Jesse's request.
whoops, turns out jesse already split this out, and forgot about it. closing as dupe. *** This bug has been marked as a duplicate of bug 871648 ***
