Re: And thus..
"systemd does not add new functionality in this area - it just does the same old stuff in a different way. This is why some of us are pushing back - what was there wasn't fundamentally broken."
If that were true, why are there constant complaints about things breaking? What I see is a bunch of bodges on top of bodges, and the thing about bodges is that they don't usually hold that well.
If I had to put it in a nutshell, I say the whole UNIX model is broken because it relies on a level of trust you can't guarantee anymore. You simply can't rely on everything in the chain to "do it well"; odds are at least one thing will "do it wrong" instead, which is why things keep breaking.
