Recently I was accepted in Google Summer of Code program and my task is to revamp pessulus lockdown editor, to bring it up to date (dconf, GTK+3, etc.).
In short, the plan is to make an lockdown editor, that is easier to use than dconf-editor with common configuration presets. The work is not only to make gsettings more accessible, but also to implement new lockdown features, if necessary.
In my next blog post I will publish list of lockdown features that the new pessulus incarnation should support, list of lockdown scenarios and default settings for those scenarios.
My projects wiki stub has some basic information. My nickname in IRC is Tranzistors and if you are interested in locking down computers, feel free to contact me.
