This actually looks sane enough that I might even boot it. Call me crazy.

LOL.

I had to go through the patch with a find comb, because everything
worked except for some reason network name resolution failed:
systemd-resolved got a permission error on

    Failed to listen on UDP socket 127.0.0.53:53: Permission denied

Spot the insufficient fixup in my cut-and-paste capget() patch:

  kdata[0].effective   = pE.val;
        kdata[1].effective   = pE.val >> 32;
  kdata[0].permitted   = pP.val;
        kdata[1].permitted   = pP.val >> 32;
  kdata[0].inheritable = pI.val;
        kdata[0].inheritable = pI.val >> 32;

Oops.

But with that fixed, that patch actually does seem to work.
