I don't see any ports dependency issues as there's been binary packages available forever. Even the install process is a lot faster than any linux I have to use at $work, not to mention easier to automate with autoinstall[0] if needed.
There are many issues with the formulation of containers on Linux (though I think people overstate it whenever bugs like this happen) but ultimately this bug was a UAF that gave you arbitrary code execution in the kernel. Zone IDs are also just numbers in kernel memory... right?

[1]Tape different things together and see if it holds.
(I've been one of the maintainers of runc -- the most widely use used container runtime on Linux -- for more than a decade, so I'm at least somewhat well-informed on the topic.)
The duct tape criticisms are fair when talking about other vulnerabilities (such as when container runtimes have misconfiguration or other inatomicity bugs) but not really here in the context of a kernel arbitrary code execution gadget. It also seems quite unlikely that the illumos kernel doesn't contain any of these kinds of bugs.
Why are you not making easy money hand over fist from these rewards? A couple of weekends of work and you can retire early.
Maybe that's exactly what these infosec companies are. And maybe you need more than "a skid with claude over a weekend" to get anything worthwhile.
... until its getting popular usage and gets targeted for vulnerability research
