Hi, A little while ago the upstream TuneD project added their own implementation of power-profiles-daemon, tuned-ppd. At a high level, both of these services provide a D-Bus API to set various power states on the system, e.g. "powersave" or "performance".
While modifying the ebuild for sys-apps/tuned to install it[1], I figured we ought to go ahead and switch the default implementation of power-profiles-daemon in its reverse dependencies to sys-apps/tuned for the following reasons: 1) The upstream power-profiles-daemon project[2] appears to have stalled, with no activity in over 8 months. 2) TuneD provides more features and more available power profiles. Some of these profiles are already well optimized for various workloads. 3) TuneD arguably has better support, having been around for more than a decade. 4) Users who wish to use power-profiles-daemon anyway can just install it manually instead of TuneD. We're only changing the default here. Looking at other distros, Fedora has already switched to using tuned-ppd[3]. Debian sid still defaults to power-profiles-daemon, but there is a separate tuned-ppd package that can provide it. Arch has no default, as both power-profiles-daemon and tuned-ppd are optional dependencies. I intend to make this change within the next week or two unless there are any outstanding concerns.
