I've recently been working with Fedora on some small disk systems (via epia with flashdisks) and every MB counts when installing these, thus I noticed that anaconda (text mode) transfered the image to the HD, which isn't necessary when installing from DVD, as no diskchanges are needed then.
We used to check this and only do it as needed; agreed that we should go back to that for the next release.
Adding FutureFeature keyword to RFE's.
This should be fixed in the next build of anaconda.
