So my question stands: What is the _recommended_ way to handle simple data types in low-bandwidth/frequency multiple-valued transactions to hardware? Examples include reading/modifying framebuffer settings (currently done through IOCTLS), s390 current state (up for discussion), etc. In these cases there needs to be an atomic snapshot or write of multiple values at the same time. Given the situation it would be _nice_ to use sysfs so the admin can do it by hand; makes things shell scriptable and reduces the number of binary compatibility issues.
