Hrm.. i guess i need to deal with errors of not finding things outside of the init method.

Also, I'm not sure why, but I can't get the sanity check step to ever fail. It always passes no matter if it finds those paths or not.

So, I'm not sure how useful this thing is. At this point, all it's solving is making the OS level pc files available.

I looked a bit at what it would take to provide development headers for the rest. I think in 99% of cases, we really only care about udev, so maybe we just have that header and pc file.

I looked at the code, and we should be able to just cherry pick the udev.h from the sources, and generate our own basic .pc file for udev. Maybe I just call this the udev wrapper instead.
The rest of systemd is just so much other stuff, and difficult to build at OS level.
