I am currently loading and unloading a prototype like security module on a regular basis. The fact that such a module can be loaded and unloaded (albeit in an unsecure way) greatly simplifies development. Thus this change will adversely affect me and probably also others that develop LSMs. Additionally deployment of and choice among legitimate security modules that may or may not (yet) be part of the main kernel tree is simplified by an option to load these security modules (e.g. at boot time) into a running kernel. This way a distribution can provide AppArmor, SELinux, SecLevl and whatever as options very much in the same way that this works for a driver. > Because I prefer my flamewars pre- rather than post-merge. You asked for oppinion. I do not plan to engage in any flamewars. regards Christian
