summary

Compares funding for nature and open source then demos several concrete tools and results: a filesystem notification server (fsnotify d-server) that delegates watch access via UID mappings and user namespaces; a user‑space xattr emulation using seccomp_notify emulator to set SELinux contexts inside unprivileged builds; an eBPF+Rust collector that samples cache misses at 1 ms and shows 20–30% slowdowns (up to 3x) from noisy neighbors; and unikernel/runtime experiments that boot minimal kernels and run in containerd. Practical, working prototypes with repo and Helm chart available.
