How does it make joyent look stupid? Dtrace is miles ahead of Systemtap, especially when it comes to installation because dtrace is generally embraced where it's being used as a default installation which systemtap is not and I don't have to make a monkey dance if I upgrade the kernel.

On a system with dtrace like OS X tracing tools like dtruss are basically just wrappers around dtrace. It's very natural to the platform.

Systemtap was out of the box on RHEL 5 update 2. No monkey dance involved.

And yet, I've seen it crash systems as late as RHEL6u2. It certainly made me very cautious about using it on production systems, which was sort of the whole point.
