Just tried respinning fedora-livecd-desktop.ks and fedora-live-desktop.ks on my Fedora 16 machine and they failed both :( This is the command used to respin iso image: livecd-creator -v -t /livecd/tmp/ --cache=/livecd/yum-cache/ -f Fedora-16-64bit-2012-04 -c fedora-livecd-desktop.ks and this is how it fails: Installing: ivtv-firmware ################### [1135/1137] Installing: iwl4965-firmware ################### [1136/1137] Installing: ipw2100-firmware ################### [1137/1137] 2278 blocks Removing password for user root. passwd: Success Note: Forwarding request to 'systemctl enable NetworkManager.service'.

Is this a known issue? Cheers, Valent.
