Systemd is a cancer, it will end up killing Linux if this goes on unchecked. At least Torvalds seems to (most of the time) know his stuff, the way they replaced the memory management left me with a bad taste but in the end it worked out. What's happening with Systemd is absolutely unpalatable and I hope that Redhat and other distros take note, there are a lot more Linux systems on servers than on Desktops and if they believe that expending all this effort on Linux on the desktop so they can better compete with Windows they might just lose their dominance on the server because of it.
Red Hat is developing systemd. It has nothing to do with making Linux palatable on the desktop, but a severe case of NIH, which to be honest is hardly new in Linux-land.
systemd won't kill Linux. Linux development is out of the hands of hobbyists and enthusiasts now and corporate users and developers don't care about the holy wars. Red Hat ships systemd, Red Hats users will use systemd and that will be that.
Their existing server customers are likely to be sitting on RHEL7 for quite some time. And i suspect that the workstation customers, mostly military as best i can tell, are in part pushing for systemd. Logind etc after all is heavily focused on multi-seats.
