I maintain my kickstart configuration files with vi and often use system-config-kickstart to discover the syntax needed for a particular configuration option. To do this I run s-c-k and copy data from the preview window. To display the preview I have to enter a root password even though it will never be used. I believe that this should be changed to a warning condition rather than an error.
Not fixed in 2.6.17-1.fc7.
No, it will be fixed in 2.6.18 which I will probably also make an FC-6 update for. I need to review my bug list to see if there's anything else I can get into this release before making it later today.
