But if > you say so... I've also run into problems with livecd-creator and was told the same thing: for best results, run with SELinux in permissive mode - not disabled and not enforcing. It was a while ago but I don't think that it was something I hit for every build. This leads me to suspect that whatever the issue is, it doesn't happen every time and the releng setup must be able to avoid whatever it is that people can (and do) hit with SELinux disabled or enforcing. Also, I think that until F20 releng was building livecds in mock chroots on el boxes (dennis, please correct me if I'm wrong) where both you and I were building livecds on fedora installs. Tim
