Hi HN, my name is Cesar, I am one of the lead developers of Sysbox ( an enhanced "runc" that enables rootless containers to act as "VM-like" environments, capable of running systemd, Docker, and even K8s inside the rootless container.See this launch HN post for details on Sysbox and use-cases:  wanted to let you know that we just released a new version of Sysbox (v0.3), which further hardens container security and brings in several other improvements and bug fixes.Development of Sysbox has been very challenging, as it's pushing the limits of rootless containers (by enabling them to seamlessly run most workloads that run in VMs).We hope you find it useful and we love to hear feedback!
