Linux Lennart Poettering has posted a status update about systemd, an init/upstart alternative. systemd is able now to replace /etc/fstab and cron, and it seems it will be the default init system for Fedora 14. He has also written a post about systemd for administrators.

I can't say I know the technical merits, but as I understand it launchd is supposed to do all this and has been open source for years. Isn't this sort of reinventing the wheel? It seems to me that if there is already a system out there for nix based systems to manage all this, shouldn't that be improved upon instead of creating something new? But it may be that these two do different things, I am not sure.

You're right about that. They've said that launchd doesn't fit on Linux very well though, and that it isn't scalable enough. To quote the rather vague explanation:

launchd is a great invention, but I am not convinced that it would fit well into Linux, nor that it is suitable for a system like Linux with its immense scalability and flexibility to numerous purposes and uses.


which you can find in the FAQ section of : http://0pointer.de/blog/projects/systemd.html

I think the explanation for that would be similar to this guy's thinking:

Design is very similar to Launchd but the implementation is certainly very different and takes advantage of a lot of Linux specific features like cgroups and SELinux and it has a few extras that launchd didn't have.

they improving it under different name, and it doesn't mean always reinventing the wheels, even reinventing isn't wrong either. first is sysvinit, then upstart, now systemd. if you give freedom to everyone doing anything under linux this is what happen for its good and bad.
