Could you build this?
No Creating a daemonless container runtime in a tiny binary requires deep systems-level Linux kernel expertise that AI coding assistants cannot independently architect.
What it would actually take: Requires low-level systems programming (likely Rust, C, or Zig) directly invoking Linux kernel syscalls for namespaces (clone, unshare, setns), cgroups v2 resource controllers, pivot_root, and overlayfs mounting. It also requires rigorous security engineering around POSIX capabilities, seccomp BPF filters, and OCI runtime specifications.
Discussion
9 comments analyzed.
Competitors mentioned: smolvm microvms, containerd, CRI-O, Docker/Podman
Concerns raised: Not a Kubernetes CRI implementation, Binary size discrepancy (1.5 MB claimed vs 1.91 MB actual), Title misleading about 'runtime' capabilities, Requires nightly Rust for optimized builds
Feature requests: kern pull command for pre-caching images, Clearer cargo install documentation with package name, Better documentation on getting started
