# Profiled families (AKS/GKE gpuStack): hydrate the recipe with the

# overlay resolves only the declaration default, and 'aicr validate'
# has no --profile flag. AKS additionally needs the pool projection

# aicr snapshot --aks-gpu-pools pools.json -o snapshot.yaml
# aicr recipe -s snapshot.yaml --intent <intent> [--platform <platform>] \
# --profile <name>=<value> -o recipe.yaml
# State the target leaf's intent/platform explicitly (the snapshot
# fingerprint supplies service/accelerator/OS but intent and platform
# default to 'any') and pass -r recipe.yaml below instead of the raw
# overlay.

One structural concern on the readiness constraints — inline. Everything else in the OKE reasoning holds up, including the driver-loaded self-falsification point, which is worth capturing in the ADR as a general trap.

Multi-persona review — feat(recipes): gpuStack profile for the OKE family
Method: 4 independent persona reviewers (Correctness/Domain · Supply-chain/CI-DX · Docs · Test-coverage) → an adversarial senior meta-reviewer that re-derived every finding from the resolved code at head f8b205c2. Tiers: 🔴 Blocker · 🟠 Major · 🟡 Minor · 🔵 Nitpick.
Recommendation: Approve with comments. 🔴 0 · 🟠 0 · 🟡 6 · 🔵 3
Overall assessment
Well-executed ADR-015 gpuStack conversion. The core architecture is sound and independently verified: a single externally-grounded control-plane signal — the NvidiaGpuPlugin add-on's state, projected from oci ce cluster list-addons via the new --oke-addons flag — qualifies both ownership axes fail-closed, at snapshot-based generation and again at the validate pre-flight, faithfully mirroring the AKS --aks-gpu-pools pattern (#1967).
The meta-reviewer confirmed the mechanisms that matter: fail-closed on a missing/wrong reading works (profile_resolution.go:196, ErrCodeInvalidRequest "reading unavailable"), the constraint is a durable generation constraint (never validation.readiness), the #1327 exactly-one-advertiser invariant holds for both values, driver-root lockstep Rule 2 is coherent, and oke-addons cannot leak into the cluster fingerprint. The prior self-satisfying-readiness objection raised earlier on this PR is fully closed by this model.
Everything that survived adjudication is a documentation-completeness or test-parity gap — nothing blocking, nothing that changes runtime behavior. The 7 inline comments carry the details; two further findings on files outside this PR's diff are noted below.
Two more findings (files not in this diff, so noted here rather than inline)
- 🟡 Minor — no
K8s oke-addonsshape section indocs/integrator/measurement-api.md. That reference has a dedicated## K8s aks-gpu-pools shapesection (L244) but no analog for the newK8s.oke-addonssubtype (keysnvidia-gpu-plugin,addon-count). Add a short parallel subsection for reference parity. - 🔵 Nitpick — sibling
--aks-gpu-poolsdoc mentions have no OKE counterpart.docs/user/agent-deployment.md,docs/integrator/data-flow.md,docs/integrator/go-library.md, anddocs/integrator/recipe-development.mdeach surface the aks-gpu-pools projection but were not extended for the identical OKE projection. Consistency drift; lowest priority.
Confirmed non-issues (examined and cleared)
- nodewright
v0.17.1 → v0.18.0is not scope creep. The PR body explicitly justifies it as an in-scope OKE cri-o dependency (short-name rejection of v0.17.1'salpine/kubectl, NVIDIA/nodewright#481), and the global golden churn it causes is disclosed. The churn is exactly right — only the two OpenShift recipes (which don't use nodewright) are unchanged instock_render_golden.yaml; unique-images 100→99 is explained (kube-rbac-proxy appeared only under nodewright, dropped by the v0.18.0 chart). - Empty
{"data":[]}→absentwhilenull/missing-datais rejected — by-design and test-pinned. - Fingerprint isolation, fail-closed on missing reading, generation-vs-readiness constraint placement, #1327 advertiser invariant, driver-root lockstep Rule 2, and dual-projection (aks+oke) independence were all re-derived from source and hold.

🟡 Minor — Committed BOM carries a non-reproducible signal: killed internal-failure warning
This warning is newly introduced by the regen — origin/main renders ### prometheus-operator-crds clean (_No images extracted._). The helm template subprocess was OOM/timeout-killed during make bom-docs, embedding an internal ErrCodeInternal string into a user-facing supply-chain doc.
Blast radius: Cosmetic — the row has 0 images on both main and head, so no silent under-reporting, and it is the only warning in the file. But no PR gate catches it (TestCommittedBOMVersionsMatchRegistry is version-table-only), and the weekly bom-refresh will churn a PR just to delete it.
Fix: Re-run make bom-docs in an unconstrained environment and re-commit so the row renders clean.

Fixed in 2651989 — re-ran make bom-docs in an unconstrained environment; the diff is exactly the two-line warning removal and prometheus-operator-crds now renders _No images extracted._ clean.

🟡 Minor — This row says the OKE gpuStack profile has "three values" — the design is two
The authoritative overlay declares exactly two values (oci-managed, operator-managed) — this is the withdrawn three-value iteration's language leaking into the shipped TOC. Every other doc in this PR correctly says two, and grep confirms this is the only stale OKE hit.
Fix: "(three values)" → "(two values)". (The PR body's Implementation Notes also still say "Why three values" — worth aligning for consistency.)

🟡 Minor — --oke-addons is documented in prose here but missing from both cli-reference flag tables
This prose adds --oke-addons, but its sibling --aks-gpu-pools also has a full descriptive row in BOTH the snapshot flag table (L103) and the validate flag table (L1050), while --oke-addons is absent from both. A user scanning the canonical snapshot/validate flag tables won't find it.
Fix: Add an --oke-addons row to both flag tables mirroring the --aks-gpu-pools rows (path to oci ce cluster list-addons --all --output json dump; projects K8s.oke-addons.nvidia-gpu-plugin installed/absent; other lifecycle states fail closed; 1 MiB cap; AICR_OKE_ADDONS_PATH; validate variant ignored with a pre-captured --snapshot).

🟡 Minor — This test records the add-on constraint but nothing resolves an OKE recipe against a snapshot to prove it fails closed
The headline behavior is fail-closed qualification, but OKE is only tested at the projection layer (okeaddons_test.go) and here at the constraint-RECORDING layer (this asserts the constraint VALUE via BuildFromCriteriaWithProfile) — never the join: resolving against a snapshot and asserting resolution FAILS. AKS has exactly that in pkg/client/v1 TestResolveRecipeFromSnapshot_GPUDriverAutoDetect (aks + absent snapshot fails the azure-managed constraint; reading … is unavailable). The eval engine is shared and verified working, so this is a test-parity gap, not a live bug — but a regression that drops the constraint, mismatches the subtype key, or passes an addon-deleting marker would ship green.
Fix: Add OKE resolve-against-snapshot cases: installed+oci-managed resolves; installed+operator-managed fails closed; absent+operator-managed resolves; absent+oci-managed fails closed; addon-deleting fails both; no oke-addons reading → reading "K8s.oke-addons.nvidia-gpu-plugin" is unavailable.
There was a problem hiding this comment.
Agreed on the gap — deferring this one deliberately: the resolve-against-snapshot cases will be shaped by the resolution of the blocking absent-semantics finding on this PR (the qualifying constraint set may change), so I'll add them together with that fix rather than write them twice.
There was a problem hiding this comment.
Done in 32d6347 — TestResolveRecipeFromSnapshot_OKEGpuStackQualification (pkg/client/v1) resolves the OKE l40s/ol chain against snapshots for all eleven qualification cases: installed/absent × both values, addon-deleting failing both, missing readings → reading … is unavailable, plus the legacy device-plugin tripwire cases (active and unknown fail operator-managed; active does not gate oci-managed).

🟡 Minor — Generalized merge/attach is never exercised with the OKE subtype or two projections at once
mergeAKSGPUPools/attachAKSGPUPools were generalized to mergeProviderProjection/attachProviderProjection iterating a []Subtype slice, but every fixture still supplies a single SubtypeAKSGPUPools projection. The new for-loop over 2+ projections is never driven with >1 element. No 0%-coverage blocker (AKS cases cover the funcs), but a regression where a second projection clobbers the first, or the OKE subtype fails to round-trip the YAML merge, ships undetected.
Fix: Add one case supplying both an aks-gpu-pools and an oke-addons subtype and asserting both land on the same K8s measurement; and one running the OKE subtype alone through mergeProviderProjection.

🔵 Nitpick — OKE warn-wrapper string/env wiring (AICR_OKE_ADDONS_PATH) untested
classifyIgnoredProjection is now parametrized by flagName but this table drives it only with "aks-gpu-pools". The OKE binding (warnIgnoredOKEAddons → env AICR_OKE_ADDONS_PATH, flag "oke-addons") has no test, so a typo in the env-var name or flag string ships undetected.
Fix: Add a classifyIgnoredProjection(..., "oke-addons") row to this table.

Done in 2651989 — the classifyIgnoredProjection table now takes a flagName and has oke-addons rows for both the explicit-flag and ambient-env (AICR_OKE_ADDONS_PATH) paths.

🔵 Nitpick — Fail-closed on non-ACTIVE add-on states depends on the operator passing --all
The "non-ACTIVE state → addon-<state> fail-closed marker" guarantee only holds if the dump lists the add-on. oci ce cluster list-addons WITHOUT --all omits removed/non-active add-ons, so a NvidiaGpuPlugin mid-DELETING would be absent from the list and project absent → silently qualify operator-managed instead of failing closed.
Fix: Not fixable from the dump alone; docs already mandate --all. Consider noting the --all dependency directly in the --oke-addons flag Usage string.
There was a problem hiding this comment.
Also deferring alongside the blocking absent-semantics finding — the --all dependency and the mid-DELETING omission you describe feed the same signal-strength question, so the Usage wording will be settled with that design.
There was a problem hiding this comment.
Done in 32d6347 — both --oke-addons Usage strings now state the --all dependency explicitly: without it, removed and non-ACTIVE add-ons are omitted from the dump and would read as absent instead of failing closed.

Reviewed the OKE gpuStack profile change. One finding is blocking:
pkg/collector/k8s/okeaddons.go:91 collapses two reachable OKE states — a cluster that never enabled the NvidiaGpuPlugin managed add-on, and one that explicitly removed it — into a single absent reading. Oracle's docs describe the add-on as optional and not deployed by default, while OKE's built-in device plugin is enabled by default and controlled separately via a node-pool flag (oci.oraclecloud.com/disable-gpu-device-plugin), not the add-ons API. A stock cluster that never touched the newer add-on can therefore read as absent, qualify operator-managed, and end up running the GPU Operator's plugin alongside Oracle's still-active default one — the same double-advertisement issue (#1327) this PR sets out to fix. The single-signal design from #2363 needs to be re-anchored against this, or the supported state space narrowed explicitly, before merge.
Three non-blocking items: two are left as inline comments (--oke-addons/--aks-gpu-pools help text omitting --cluster-id, and a killed helm template run committed into the BOM doc). The third has no line in this diff to anchor to: pkg/snapshotter/agent.go:412, inside mergeProviderProjection (renamed in this PR from mergeAKSGPUPools), still wraps its serialize error as "failed to serialize snapshot after AKS GPU pools merge" — the other three error strings in that function were genericized, this one and two nearby doc comments (around lines 537 and 1014) weren't. Cosmetic, but worth a follow-up commit since the function is now shared by the OKE path.
Requesting changes on the blocking item; the rest can land alongside it.

Defaulting to absent whenever NvidiaGpuPlugin is missing from list-addons conflates two distinct, both-reachable states: a cluster that never explicitly enabled the managed add-on, and one that explicitly removed it to hand ownership to the operator. Oracle documents the add-on as optional and not deployed by default, while OKE's built-in device plugin — a separate, older mechanism controlled by the oci.oraclecloud.com/disable-gpu-device-plugin node-pool flag, not the add-ons API — is on by default. A stock cluster that simply never touched the newer add-on has no entry here, reads as absent, and qualifies operator-managed even though Oracle's default plugin may still be actively advertising nvidia.com/gpu. Deploying operator-managed there installs the GPU Operator's plugin on top of it, reproducing the double-advertisement this PR is meant to fix (#1327), and contradicting the PR's own premise that OKE auto-installs the device plugin on every cluster.
The qualification signal needs to distinguish "never provisioned" from "explicitly removed," or the supported configuration needs to be narrowed to clusters that have explicitly adopted the managed add-on.

You're right, and I can confirm it empirically — I checked two of our live OKE clusters:
A ~13-month-old v1.31 cluster: kube-system/nvidia-gpu-device-plugin is running — labeled addonmanager.kubernetes.io/mode: Reconcile, i.e. the legacy Kubernetes addon-manager, not the OCI cluster add-ons API. It targets GPU nodes via nodeAffinity (nvidia.com/gpu=true or an enumerated legacy shape list), skips nodes carrying the disable-gpu-device-plugin label, and is invisible to oci ce cluster list-addons. It is running alongside the GPU Operator's device plugin on that cluster today — exactly the double-advertisement you describe, and the projection can't see it.
A current-generation v1.34 enhanced cluster (explicit add-on set at creation): the NvidiaGpuPlugin add-on was never enabled, no node has the disable label, the legacy DaemonSet doesn't exist at all, and the operator's plugin runs alone. On clusters built this way, absent → operator-managed is correct — and requiring the disable label as a second qualification signal would fail closed on exactly this cluster, so I'm not proposing that.
Oracle's docs frame both mechanisms but not the boundary: the add-ons overview says optional add-ons (including NvidiaGpuPlugin) are "not deployed by default" and are manageable only on enhanced clusters; the add-on's configuration page shows it manages the same kube-system/nvidia-gpu-device-plugin DaemonSet the legacy path deploys; yet the GA announcement says the plugin "is automatically installed for all new OKE clusters," and no release note documents where auto-install stops. Since provisioning data cannot predict whether the legacy DaemonSet exists on a given cluster, I want to detect it rather than assume:
- Qualification unchanged: add-on
installed→oci-managed,absent→operator-managed, non-ACTIVE lifecycle states fail closed (as in this PR). The add-ons API is where Oracle is consolidating (they now ship GPU Operator and Network Operator add-ons too), so it stays the canonical signal. - Fail-closed tripwire: the snapshot additionally detects the legacy plugin (the
addonmanager.kubernetes.io/mode: Reconcile-labelednvidia-gpu-device-pluginDaemonSet inkube-system, evaluated against GPU nodes). If present and not fully disabled, both profile values fail qualification with remediation — disable it via the node-pool label or migrate to the managed add-on, then re-snapshot. A legacy cluster never silently qualifies either value. This is detection of an Oracle-owned artifact we never deploy, so it stays externally grounded — not the self-satisfying ClusterPolicy readback we rejected in recipes: design grounded qualification for the OKE gpuStack profile #2363. - Scope note: qualification is defined for enhanced clusters. That's not a practical restriction — enhanced is the default type, has no cost premium, and self-managed GPU/HPC nodes require it. On a basic cluster
list-addonscan't produce a valid dump, so qualification already fails closed; the remediation will point at upgrading to enhanced (a supported in-place operation).
Two questions before I implement:
- Does the tripwire resolve the blocker, or do you want "never enabled vs. removed" distinguished more strongly? (The add-ons API is stateless; that distinction isn't recoverable from provisioning data.)
- For legacy clusters wanting
oci-managed: fail closed and require migrating to the managed add-on first (my preference — one canonical signal), or accept the legacy DaemonSet as an alternativeoci-managedqualifier?
I'll fold the deferred test items (resolve-against-snapshot fail-closed cases, the --all Usage note) into the same change once this is settled.

One correction to point 2 after working through the implementation: the tripwire constraint should attach to operator-managed only, not both values. When the managed add-on is enabled, it manages the same kube-system/nvidia-gpu-device-plugin DaemonSet (the add-on's configuration page confirms the ConfigMap "is referenced by the nvidia-gpu-device-plugin daemonset") — so an oci-managed cluster always observes an "active" DS, and gating that value on the tripwire would make it permanently unqualifiable.
The outcome matrix still delivers the guarantee that matters — a legacy cluster never silently qualifies either value:
| Cluster state | oci-managed |
operator-managed |
|---|---|---|
| Add-on installed (DS is add-on-managed) | ✅ | ❌ add-on constraint |
| Add-on absent, no legacy DS | ❌ add-on constraint | ✅ |
| Add-on absent, legacy DS active | ❌ add-on constraint (remediation: migrate to the add-on) | ❌ tripwire |
| Legacy DS present but fully disabled (desired 0) | ❌ add-on constraint | ✅ |
On the legacy-cluster row, oci-managed fails through the existing installed constraint rather than the tripwire — same fail-closed result, and it doubles as the answer to my second question if you agree: legacy clusters wanting oci-managed migrate to the managed add-on rather than being accepted as-is. The rest of the proposal is unchanged.

Implemented in 32d6347 (appended commit — if you'd prefer a different shape after reviewing, we revert it cleanly):
- New in-cluster reading
K8s.oke-legacy-plugin.nvidia-gpu-device-plugin(pkg/collector/k8s/okelegacyplugin.go): a read-only get of thekube-system/nvidia-gpu-device-pluginDaemonSet, keyed on theaddonmanager.kubernetes.io/mode: Reconcilelabel so an unrelated same-named workload doesn't trip it. Collapsed tonone/active/unknown(uncollapsed detail under…daemonset);unknown— including a clientless snapshot — fails constraints closed, so "could not look" never reads as "not present". The agent ClusterRole gains read-onlyapps/daemonsets. operator-managednow requires the readingnone; per the addendum,oci-managedis deliberately not gated (the installed add-on reconciles the same DaemonSet name). The full matrix from the addendum is pinned byTestResolveRecipeFromSnapshot_OKEGpuStackQualification— eleven resolve-against-snapshot cases including: legacyactivefailsoperator-managed; legacy cluster (add-on absent + DS active) qualifies neither value; missing either reading →reading … is unavailable.- Remediation text names both routes: disable per GPU pool via
oci.oraclecloud.com/disable-gpu-device-plugin=true(supported for the legacy DaemonSet, unlike the add-on route), or migrate to the managed add-on. - Docs:
oke-gpu-setup.mdgains the legacy-detection section, a second qualification matrix, and the enhanced-cluster scope note;measurement-api.mdgains the subtype shape;component-catalog.mdgains the tripwire paragraph.
The two deferred items from the other threads (resolve-against-snapshot fail-closed tests, the --all usage note) are folded into the same commit.

This example (oci ce cluster list-addons --all --output json) omits --cluster-id, which the OCI CLI requires — following it as written exits without producing a dump. docs/integrator/oke-gpu-setup.md has the correct form with --cluster-id <cluster-ocid>; worth matching it here.

Fixed in 2651989 — added --cluster-id <cluster-ocid> here and swept every other list-addons example repo-wide (validate.go, snapshotter godoc/error strings, okeaddons.go, docs, and the overlay's constraint message) so they all match oke-gpu-setup.md.

This reads as an artifact of a killed helm template run rather than an accepted result — the prometheus-operator-crds render didn't complete, so its image list is silently incomplete. make bom-docs should be rerun until this chart renders successfully rather than committing the failure warning.

Agreed — fixed in 2651989. Re-ran make bom-docs until prometheus-operator-crds rendered successfully; the committed doc no longer carries the failure warning.

…jection Declares the two OKE cluster shapes as an ADR-015 gpuStack profile on the oke-ol family overlay: oci-managed (Oracle GPU image driver + the NvidiaGpuPlugin add-on advertising, advertiser: external) and operator-managed (bring-your-own driverless image with the add-on removed; the operator owns driver, toolkit, plugin, and the DRA root). MOFED is host-supplied in both values. The hybrid image-driver + operator-plugin shape is deliberately not declared — no consumer needs it, and the two-value model lets one control-plane signal qualify both ownership axes. Qualification (#2363, decided): the NvidiaGpuPlugin add-on's control-plane state, projected from an operator-supplied `oci ce cluster list-addons --all --output json` dump via a new --oke-addons flag on aicr snapshot and aicr validate — the AKS --aks-gpu-pools pattern (#1967) end to end: fail-loud file projection before any cluster work, controller-side merge in agent Job mode, validate re-captures with the same flag. installed → oci-managed, absent → operator-managed; any other lifecycle state projects a marker no constraint accepts, and a snapshot captured without the flag fails closed as reading-unavailable. Per-node label disablement (oci.oraclecloud.com/disable-gpu-device-plugin) is out of contract: it leaves the add-on installed. No ClusterPolicy readback, no driver-state gates, no readinessConstraints. Mechanism: pkg/collector/k8s/okeaddons.go (projection + normalization), K8s.oke-addons catalog row, snapshotter attach/merge (the AKS-named helpers generalize to attachProviderProjection/mergeProviderProjection), CLI flags with AICR_OKE_ADDONS_PATH, surface golden. gpu-operator values-oke.yaml drops the static driver/toolkit stanzas (profile-owned) and adds DEVICE_LIST_STRATEGY + MOFED_ENABLED devicePlugin env; the DRA values-oke.yaml drops nvidiaDriverRoot (profile-owned).

…-managed Older OKE clusters ship the NVIDIA device plugin through the legacy Kubernetes addon-manager (a kube-system/nvidia-gpu-device-plugin DaemonSet), which `oci ce cluster list-addons` cannot see - so a legacy cluster reads the NvidiaGpuPlugin add-on as absent, qualifies operator-managed, and the GPU Operator's plugin double-advertises nvidia.com/gpu alongside Oracle's (#1327). Review finding on this PR. Add an in-cluster tripwire, constrained by operator-managed only: - New K8s sub-collector (oke-legacy-plugin subtype): a read-only get of the DaemonSet, collapsed to none/active/unknown (detail preserved under the daemonset key). Unknown - including a clientless snapshot - fails constraints closed; "could not look" never reads as "absent". - The agent ClusterRole gains read-only apps/daemonsets. - operator-managed requires the reading none; oci-managed is deliberately not gated (the installed add-on reconciles the same DaemonSet name, so it would observe active on every healthy cluster). A legacy cluster therefore qualifies neither value: oci-managed fails via the add-on constraint (remediation: migrate to the add-on), operator-managed via the tripwire (remediation: per-pool disable label or add-on migration). Also folds in the two deferred review items: resolve-against-snapshot fail-closed tests covering the full qualification matrix, and the --all dependency note in the --oke-addons usage strings.

Thanks for addressing the review findings. The current code changes are substantively approvable, including the legacy device-plugin tripwire and the CLI/BOM fixes. Before approval, please rebase onto current main and resolve the reported conflict, then let the required checks rerun. Please also update the PR description to match the current two-value design: the Implementation Notes, Behavior change, and Rollout notes still refer to the withdrawn three-value model and the old oci-default/operator-plugin names. Once the rebased diff is unchanged in substance, the description is current, and the required checks are green, this is ready for approval. |

Summary
Converts the OKE family to the ADR-015
gpuStackconfiguration profile with two values —oci-managed(Oracle GPU image driver + theNvidiaGpuPluginadd-on advertising) andoperator-managed(bring-your-own driverless image with the add-on removed; the operator owns driver, toolkit, plugin, and the DRA root) — qualified by a new OCI add-on projection:aicr snapshot|validate --oke-addons <oci ce cluster list-addons --all --output json dump>projects the add-on's control-plane state intoK8s.oke-addons.nvidia-gpu-plugin, and each value carries the matching durable constraint (installed/absent), evaluated at snapshot-based generation and re-evaluated by the validate pre-flight.Motivation / Context
OKE auto-installs NVIDIA's device plugin on every cluster, yet the OKE recipe leaves the GPU Operator's plugin enabled — a stock cluster double-advertises
nvidia.com/gpu(#1327).values-oke.yamlalso documented the operator-managed driver flip as a manual four-path--setprocedure, and hardcodednvsentinel.labeler.assumeDriverInstalled: truechain-wide.Design provenance: this implements the #2363 decision (settled with @yuanchen8911 on Slack). Two values, not three — the hybrid image-driver + operator-plugin shape has no consumer, and dropping it collapses both ownership axes onto one distinguishing signal (the GKE #2360 move). Qualification uses an external provisioning signal only: not ClusterPolicy readback (#2363 Option C, self-satisfying), not
GPU.hardware.driver-loaded— theNvidiaGpuPluginadd-on's actual control-plane state, mirroring the AKS--aks-gpu-poolsprojection (#1967) end to end (fail-loud file projection before any cluster work, controller-side merge in agent Job mode,validatere-captures with the same flag). Any non-ACTIVE lifecycle state projects a fail-closed marker; a snapshot captured without the flag fails closed as reading-unavailable. Per-node label disablement (oci.oraclecloud.com/disable-gpu-device-plugin) is out of contract — it leaves the add-on installed; clusters using it (e.g. NVCF today) migrate to add-on removal, the shape DGXC'sterraform-oci-okeclusteralready produces (NvidiaGpuPlugin = { remove = true }, verified on a live cluster). A supported-image consistency check is tracked as #2363 follow-up.Fixes: N/A
