This talk is a follow-up for LPC 2025 "seccomp listeners for nested containers" from "Containers and Checkpoint/Restore" MC [1].
I'll give an update of patch-set progress in LKML, overview of technical challenges. In case if it is merged upstream by the time of this talk at FOSDEM, I'll show a demo of this feature and give a detailed overview of implementation and potential future improvements.
