That is all true. The "power manager in userspace" was meant to prove a point: that this _could_ be done without invasive changes to the kernel. It wasn't necessarily meant to be a _better_ solution. > So, for a phone-like system, where you'd generally want to simplify user space, > having a "power manager" in the kernel seems to make sense to me. This is a judgment call. Obviously different people have different opinions.
