After the troubles I've been having with it, I wonder if anybody has had any success with it. Seems that it's not in RHEL5 either.
I have a diskless FC6 box working, but not out of the box (cf FC4 which just worked). I added the changes I had to make to the mythtv.org wiki -off the top of my head the only one I can remember is the mount.nfs change you already know about, but there info on the wiki is more or less complete I think. As for fedora not offering a diskless client - ROTFL. A diskless client served from a redhat server is going to be a little sloooow I think. But system-config-netboot has been around for a while.
