Okay. Thank you for explaining. (Including the below.)

I know how to code, and spend significant portions of my day doing so.
I'm familiar with C, having been using it for the better part of two
decades. But I've never dug into the Linux kernel, simply because it's
a huge amount of code to grok; and opening up a few source files won't
tell me why people are unhappy. (Unless it's all in comments, in which
case it's no different from reading text files.)

Uhh, XML config files don't belong ... pretty much anywhere. :)

That's something that's happened a good few times.

It was developed at Red Hat. Are you saying they're trying to subvert
open source, or someone else is? I'm lost.

I did not, but I did learn other tools which would let me target
Windows (mainly Open Watcom C/C++, then, but if I knew then what I
know today, probably Python or Pike).

As I said above, I can code. (Most of my need for Upstart/systemd
scripts is to get my stuff running on startup.) But maybe I should
start targeting a BSD, if only to get some experience with it.

You say there'll be a fork in the Linux kernel. But if the split is
over the use of systemd, why isn't there simply a fork of a
distribution, shipping some other init instead of systemd?

Maybe I should just shut up and go be a user. :|
