Description of problem: The Fedora project has been reluctant to publish installer updates once a version has gone gold. In the past that wasn't that big of a deal, but now that doing respins has been made easy, this is a bit of an annoyance. There have been updates.img files made to take care of some critical problems, but they aren't in a convenient place for people running revisor. My suggestion is that there be an anaconda-updates package created for handling critical installer bug fixes. Perhaps initially (for a given Fedora version) this package could produce an empty file system. And then updates to the installer could be added as critical installer issues are fixed.
Is using the Fedora Unity respin for Fedora 8 good enough for you? That fixes a variety of these critical sorts of issues with entirely new installation media: http://fedoraunity.org/news-archives/fedora-8-re-spin-released
In the short run sure. I was hoping in the long run that Unity's work would get back into Fedora during the term of a release, rather than the following release.
