I don't know much about desktop environment infrastructure, but I think
the kernel probably already has a lot of what's needed for LinuxApps.

Tools like Sandstorm [1] (shameless plug, but it's a good example here)
can already sandbox normal-ish programs, and those sandboxes can be
launched without privilege [2].

Why is kdbus needed?  Why are overlays better than, say, btrfs
lightweight copies here?  Also, overlayfs might actually make it for 3.19.

As for childfs, I implemented procfs polling a couple years ago, but it
never went anywhere:

If that would help, I can try to dust it off and get it in to the kernel.
