Details 
- dev-vm.sh: rewrite for macOS (bsdtar ISO extraction, Homebrew mkfs.ext4
  detection, direct kernel boot, TCG acceleration, port 8080 forwarding)
- inject-kubesolo.sh: add CA certificates bundle from builder so containerd
  can verify TLS when pulling from registries (Docker Hub, etc.)
- 50-network.sh: add DNS fallback (10.0.2.3 + 8.8.8.8) when DHCP client
  doesn't populate /etc/resolv.conf
- 90-kubesolo.sh: serve kubeconfig via HTTP on port 8080 for reliable
  retrieval from host, add 127.0.0.1 and 10.0.2.15 to API server SANs
- portainer.go: add headless Service to Edge Agent manifest (required for
  agent peer discovery DNS lookup)
- 10-parse-cmdline.sh + init.sh: add kubesolo.edge_id/edge_key boot params
- 20-persistent-mount.sh: auto-format unformatted data disks on first boot
- hack/fix-portainer-service.sh: helper to patch running cluster

e372df578b feat: initial Phase 1 PoC scaffolding for KubeSolo OS 
Complete Phase 1 implementation of KubeSolo OS — an immutable, bootable
Linux distribution built on Tiny Core Linux for running KubeSolo
single-node Kubernetes.

Build system:
- Makefile with fetch, rootfs, initramfs, iso, disk-image targets
- Dockerfile.builder for reproducible builds
- Scripts to download Tiny Core, extract rootfs, inject KubeSolo,
  pack initramfs, and create bootable ISO/disk images

Init system (10 POSIX sh stages):
- Early mount (proc/sys/dev/cgroup2), cmdline parsing, persistent
  mount with bind-mounts, kernel module loading, sysctl, DHCP
  networking, hostname, clock sync, containerd prep, KubeSolo exec

Shared libraries:
- functions.sh (device wait, IP lookup, config helpers)
- network.sh (static IP, config persistence, interface detection)
- health.sh (containerd, API server, node readiness checks)
- Emergency shell for boot failure debugging

Testing:
- QEMU boot test with serial log marker detection
- K8s readiness test with kubectl verification
- Persistence test (reboot + verify state survives)
- Workload deployment test (nginx pod)
- Local storage test (PVC + local-path provisioner)
- Network policy test
- Reusable run-vm.sh launcher

Developer tools:
- dev-vm.sh (interactive QEMU with port forwarding)
- rebuild-initramfs.sh (fast iteration)
- inject-ssh.sh (dropbear SSH for debugging)
- extract-kernel-config.sh + kernel-audit.sh

Documentation:
- Full design document with architecture research
- Boot flow documentation covering all 10 init stages
- Cloud-init examples (DHCP, static IP, Portainer Edge, air-gapped)
