## What Adds `build/` — a Dockerfile with `mesa-build`, `nestri-build`, `os-base`, `runtime`, `runtime_prod` and `runtime_debug` stages, plus the `etc/` overlay, `mkimage.sh` and a `Makefile` — laid out the way [borealis](https://chromium.googlesource.com/chromiumos/overlays/board-overlays/+/main/project-borealis) lays out its own `build/`. This moves the guest rootfs formula into this repo, targeting the four open guest components already here: `nescope`, `neshub`, `neswire`, `nescapture`. ## Two structural properties worth calling out - **No privileged host chroot.** A bare `chroot` into a hand-extracted rootfs needs `/proc`, `/sys`, `/dev` bind-mounted in first. `os-base` here is `FROM artixlinux/artixlinux:base-openrc` directly with `pacman -S` as plain `RUN` steps — a Docker build step already has its own `/proc`/`/sys`/`/dev`. - **No host-side ownership bug to guard against.** `COPY --from=` runs as root inside the build with no invoking-user uid in the loop. ## Scope boundary **Deliberately excludes Proton and Valve's `steamclient.so`** — both closed, and `CLAUDE.md` forbids closed content in this repo. `runtime_prod`, tagged `nestrilabs/nestri:base`, is a complete, bootable, Steam-less image — and also the shared foundation other builds start from. Whatever layers Proton/Steam on top of it is a closed build outside this repo, by design. ## Known gap Nothing starts a payload yet — `nesinit` isn't open code — so `/etc/init.d/nescope` boots it in plain-compositor mode (no command after `--`) rather than running a game. Real and testable, just not a full session yet. Details in `build/README.md`. ## Status Built and tagged locally as `nestrilabs/nestri:base` (podman, no `--no-cache` issues, greptile's three findings all fixed and verified against a real build). Not yet packed into a disk image or run inside nesbox. 🤖 Generated with [Claude Code](https://claude.com/claude-code) <!-- greptile_comment --> <h3>Greptile Summary</h3> The PR adds a multi-stage Artix/OpenRC guest-rootfs build for the open Nestri components, with production and debug image flavors. - Builds patched Mesa and the Rust workspace in dedicated builder stages. - Assembles and configures the bootable guest environment and OpenRC services. - Packs a selected container image into an ext4 root filesystem while retaining rootless container storage access. <h3>Confidence Score: 5/5</h3> The PR appears safe to merge. No blocking failure remains. <h3>Important Files Changed</h3> | Filename | Overview | |----------|----------| | build/Dockerfile | Defines the complete multi-stage build, overlays repository-root-relative configuration paths, and creates production and debug runtime targets. | | build/Makefile | Provides consistent image build and packing targets using a repository-root context and matching image tags. | | build/scripts/mkimage.sh | Keeps container-runtime operations in the invoking user's storage while escalating only filesystem creation and mounting operations. | | build/etc/conf.d/nestri-user-env | Supplies the shared service environment and export function required by the OpenRC service scripts. | | build/etc/init.d/guest-net | Configures optional guest networking from kernel parameters or stable defaults. | | build/etc/init.d/neswire | Starts the audio sink after its dependencies and pins it as the PipeWire default once the graph is ready. | <h3>Flowchart</h3> ```mermaid %%{init: {'theme': 'neutral'}}%% flowchart TD A[Arch builder] --> B[Mesa build] A --> C[Nestri workspace build] D[Artix OpenRC base] --> E[Common runtime] B --> E C --> E F[build/etc overlay] --> E E --> G[runtime_prod] E --> H[runtime_debug] G --> I[Container image] H --> J[Debug container image] I --> K[mkimage.sh] J --> K K --> L[ext4 rootfs] ``` <sub>Reviews (6): Last reviewed commit: ["refactor(build): rename the published im..."](https://github.com/nestrilabs/nestri/commit/6fecc8cc31bc425db952193074d4b9b0f861de89) | [Re-trigger Greptile](https://app.greptile.com/api/retrigger?id=58981739)</sub> <!-- /greptile_comment -->

# WirePlumber, trimmed to what a microVM with no sound card actually needs.
|
|
#
|
|
# The goal is that `neswire` is the *only* Audio/Sink in the graph, so
|
|
# default-node selection has exactly one candidate and cannot pick wrong.
|
|
#
|
|
# The "Dummy Output" (`auto_null`) sink is not disabled here, and no longer
|
|
# needs to be: it came from pipewire-pulse's `module-always-sink`, and
|
|
# pipewire-pulse is no longer installed. WirePlumber ships
|
|
# scripts/fallback-sink.lua, which creates a node by the same name, but no
|
|
# component in wireplumber.conf references it, so it never loads. If auto_null
|
|
# ever comes back, it came back with pipewire-pulse -- the switch is
|
|
# `pulse.cmd.always-sink = false` in a pipewire-pulse.conf.d drop-in, not
|
|
# anything on this side.
|
|
#
|
|
# pipewire.conf's Dummy-Driver / Freewheel-Driver are a third thing again:
|
|
# support.node.driver objects with no ports -- drivers, not sinks, so nothing
|
|
# can play into them. Dummy-Driver is load-bearing here. With no ALSA hardware
|
|
# it is what clocks the graph, and therefore what paces neswire's sink. Do not
|
|
# disable it.
