BPF Portability and CO-Re (Compile Once Run Everywhere)

It's still a huge problem. Only dTrace runs everywhere: BSD, Solaris, Mac, windows, Linux. BPF only runs on Linux.

In userspace everybody has dTrace probes, nobody has bpf/stap probes.

Additionally dTrace is secure, BPF is insecure.

It really looks bad, but these Linux jokers still think they rule the world.
