I just gave you an example, and you ask for examples? What are you, stupid?
Your problem was not a problem with init. Systemd will not solve the problem where you need NFS to boot, and NFS shits itself because it is shit.
Give us an actual example where init itself caused you a problem, or admit that you're just making shit up so that you can justify new and shiny. You're calling me stupid for insisting that you provide an actual example of a failure of init when what you provided was an example of a failure of the networking setup which could have also occurred with systemd if you misconfigured it. Now, provide an actual example of a failure of init, or if this was somehow init's fault (did it really start two init scripts at once all on its lonesome, or did the first script exit before it was done?) then explain that, and don't just describe a problem with scripts (which could also happen by misconfiguring a unit file) or with a daemon. From your description, it sounds a lot more to me like a problem with your distribution's network setup system, whatever that looks like.
