"...by gluing GDM to Systemd, the Systemd developers made it very difficult for distributors to support other init systems. They basically forced everybody to switch..." I'm sorry but I don't buy this, I think you and those sysadmins missed something. The situation with consolekit was so bad that something had to be done about it, if you were blindsided by it, you probably weren't paying attention to that area until it was too late. That's unfortunate but it doesn't really make sense to blame the systemd developers for "making it difficult" when they were the only ones trying to actually solve the problem at that time. IIRC the upstart developers never made progress on this.
