SMF/Predictive Self Healing: Graphing service dependencies

I don't have the next tutorial entry ready yet, but Stephen posted something so cool on his blog that I had to show it to you all.

Now that every service on a system is an entity with dependencies, one of the side benefits is that you can actually chart what your system looks like, graphically. Below is a chart from Stephen's machine, representing not only all of his running services and their dependencies, but a right-to-left timeline of the boot sequence of his machine:

I really can't get over how cool this is.

Stephen gives a nice overview of the features of this graph in his blog entry, so I won't reproduce them here. But go check it out. SMF is letting us do some amazing things.
