Sure. Others have stated this much better than I can, but the ideas came to me as soon as I started seeing what systemd does in Arch Linux, about a year ago. It not only takes the responsibilities of an init system, but also the functions of udev, dbus, system logging, and possibly others.
In my opinion, this major bundling of functionality reduces my software freedom of choice. It does not fit with the Linux principle of "do one thing and do it right".
Maybe my thinking is unsound, but that is the way I feel about it.
Thanks,
Tim
