Complete smolBSD platform expertise — the entire framework for building minimal NetBSD microVMs. Covers full lifecycle: SMOLerfile (Dockerfile-compatible) authoring, manual service directory creation, the dual build system (smoler.sh high-level vs bmake low-level), mkimg.sh image creation internals, startnb.sh QEMU/Firecracker PVH boot (~10ms), OCI registry push/pull (oras), networking & port publishing, bidirectional VirtIO sockets, BIOS/baremetal boot with confkerndev kernel slimming, GitHub…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# smolBSD — Complete Platform Reference This skill provides exhaustive knowledge of the entire smolBSD framework — enough for an agent to understand, navigate, extend, and debug every aspect of the project. **Read §20 (Debugging Playbook) before touching anything related to image minimization, sailor, or login/PAM in a stripped image** — these are the areas that have produced the most subtle real-world failures and are easy to misdiagnose from source alone. ## 1. Project Overview **smolBSD** builds minimal, fast-booting NetBSD virtual machines (microVMs). Key properties: - **~10 ms boot** via PVH (PVHv2) on QEMU `microvm` machine type - **No prior NetBSD installation** required on the host - **Immutable by design** — images are built once, booted many times - **Host platforms**: GNU/Linux, NetBSD, macOS (x86 VT-capable or ARM64 CPU recommended) - **Guest architectures**: `amd64`, `i386`, `evbarm-aarch64` - **VMMs**: QEMU (primary), Firecracker, Bhyve (BIOS mode) - **Images** are raw `.img` disk files with FFS (NetBSD) or ext2 (Linux build hosts) The fundamental unit is a **service** — a directory containing: - NetBSD set selection (`base`, `etc`, `comp`, `man`, `rescue`, …) …

How to install
mdr add netbsdfr/smolbsd/smolbsd@sha256:94b8772adb5ab9b2The line at the top of this page pins the label v3.2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
