Turns an image, or a machine already provisioned, into a single self-contained artifact that runs on another compatible host. Use when shipping a prepared environment as one file, when a packed artifact runs but the state installed into it is missing, when pack create fails because the VM it boots to pull or export could not start, when an older release refuses to export a branched machine, or when deciding whether to pack from an image or from a machine. Do not use it to keep a machine you…
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
# Packing a machine into a portable artifact Verified on **smolvm v1.29.0** on macOS arm64, 2026-10-15, and on **v1.14.6** on Linux aarch64, 2026-09-11; the Linux host could not run the packing steps on v1.18.2 or v1.22.2, for the reason in "Platform arms". Done means the artifact runs a command in a real VM and, for a machine pack, **the state you installed is still inside it**. The Linux runs used the scripts of their date; this version's preflight and cleanup scripts ran on Linux aarch64 on v1.22.2 on 2026-10-03. **The assertion that matters is a value, not a boot.** A pack that lost its rootfs still boots, still prints a guest kernel and still exits zero. The only thing that separates a good artifact from an empty one is a marker written into the source machine before packing and read back out of the artifact afterwards, which is what `pack-machine.sh` and `verify-pack.sh` do between them. ## Procedure **1. Preflight.** Read-only: starts no VM, packs nothing. ```bash scripts/preflight.sh ``` The lines to read are `exporter_memory_ok` and `image_vm_memory_ok`: both pack paths boot a helper VM before they …

How to install
mdr add smol-machines/smolvm/pack@sha256:63c41d8ad2697efcThe line at the top of this page pins the label git:20261016.432b170, 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.
