Michal said no and he said > that he wants a new kernel option instead. Just for the record. I didn't say I _want_ a config option. Do not misinterpret my words. I've said that a config option would be acceptable if there is no way to deliver the functionality via kernel package automatically. You haven't provided any argument that would explain why the kernel package cannot add a boot option. Maybe there are some but I do not see them right now. -- Michal Hocko SUSE Labs
