livecd-creatorprocess turns defunct. I just got things working inside a virtual machine. Same Fedora version, same software version. Could this be a hardware issue? Or maybe some package conflict? I don't know. All I know is I won't try to build a Live CD outside the virtual machine (at least not so soon).
Now I'm going to try Revisor inside the virtual machine. If it works, I'll be very happy, surely. Revisor is great. I used it to build some custom installation CDs of Fedora and CentOS, it worked pretty well, but I never got a live media built with it, unfortunately.
Let's see if, like
livecd-creator, Revisor works well under a virtual machine.
