@i-Pear Could you review this PR? Thanks!

Looks good to me, thanks. The code here is identical to #2580.

By the way, what's the difference between pkg/gadgets/run and pkg/operators/ebpf? Is the latter meant for use on k8s?
And for future uprobe features, do I need to implement changes in both places?

I'd change authorship to you in that case - or do you want to open a PR yourself?

With #2512, we just merged an overhaul of the architecture regarding image based gadgets (pkg/operators/ebpf etc.) - the run gadget pkg/gadgets/run will be removed soon. So if possible, please try to migrate the code to the new operator and feel free to ask questions around it and let me know if you need any help.

Thanks, I understand, will soon rebase my next PR onto pkg/operators/ebpf.

Let's merge this first, after that I will change my workspace to pkg/operators/ebpf.

@flyth feel free to merge if the CI does not reveal any problems.
