Fixed. The vendor tarball was repacked with azldev comp prepare-sources -p kata-containers --allow-no-hashes and the real post-overlay digest is now pinned:
aa029a4bc258ef4d13b0c219230112e20a95957cf302c02307919a28b85165c79586b525274232b00b15dc161c7e21093d1c33b45d5d3856dfe1123ad112f62d
specs/k/kata-containers/sources and locks/kata-containers.lock were regenerated (azldev comp render + azldev comp update), and both render --check-only and update --check-only now pass with no drift. The SRPM/RPM build succeeds against this digest, confirming it matches the repacked archive.

Remove the Windows-only static import libraries from the vendored-dependencies
archive via file-remove overlays: the winapi-*-pc-windows-* crates and the
windows_*_{gnu,gnullvm,msvc} (windows-targets) family. These crates are
target-gated to Windows and never built on Linux, but their lib/ import
archives (.a/.lib) ship ~1.6M ar members in aggregate (vendored several times
per arch/toolchain) and are flagged during source package signing. Only the
lib/ archives are dropped; each crate's Cargo.toml/src/checksum skeleton is
kept so cargo's resolve stays intact. The repacked archive is pinned via the
source-files SHA512, and the release is bumped for the changed source.

nit(non-blocking): This comment doesn't seem necessary, and in the fullness of time will be incorrect. We don't need to explain why we're bumping the release.

Removed — the "why we bump" comment is gone; the release overlay is now the standard azl_release fold, which is self-explanatory.

issue(blocking): Why are you doing this via a manual Release change? Is there a compelling reason not to use azl_release = 2 instead? Is it because of rcrel or something?
There was a problem hiding this comment.
Good call — switched to the azl_release idiom (matching rubygem-rake / java-25-openjdk). Added azl_release = "1" under [build.defines] and a single spec-set-tag overlay that folds it into upstream's Release:
Release: %[1 + %{azl_release}]%{?rcrel}%{?dist}
rcrel wasn't the reason — it composes cleanly. Rebuilt in mock: the RPM is kata-containers-3.26.0-2.azl4.x86_64 (so %[1 + %{azl_release}] evaluates to 2 as expected), and the generated kata-containers.azl.macros sidecar is committed.

nit(non-blocking): However you end up bumping the release (see https://github.com/microsoft/azurelinux/pull/18706/changes#r3935292816), I'd prefer that overlay to live near the declaration that this is a manual release component (in this case, that's at the top of the file).

Done — the azl_release define and the release spec-set-tag overlay now live at the top of the file, immediately under release = { calculation = "manual" }.

issue(blocking): Won't azldev component render handle the changelog for you?
There was a problem hiding this comment.
kata's spec doesn't use %autochangelog, so render does not synthesize a changelog entry — I verified it leaves the changelog as upstream's 3.26.0-1. Following the rubygem-rake convention (manual release calc + azl_release, non-autochangelog), I dropped the manual changelog overlay entirely; the azl_release bump plus the commit history is the record. Happy to add a manual entry instead if you'd prefer one here.

Fixed the wording. The comment now says these crates are never compiled on a Linux build — explicitly noting the vendor archive is fully unpacked in %prep, but cargo only verifies manifests for crates it actually builds — rather than implying selective extraction.

The PR description was already updated to match the config before this pass — it now states "No manual changelog entry is added — kata's spec isn't %autochangelog", so the description/rendered-spec inconsistency is resolved (this review ran against the earlier description).
On whether to add the entry at all: I'm following the maintainer guidance in this thread (r3935306771 / r3935292816) and the rubygem-rake precedent — a manual-release azl_release bump on a non-%autochangelog spec carries no AZL %changelog entry; the azl_release counter plus commit history record why the rebuild exists. Tobias Brick (@tobiasb-ms), happy to add a 3.26.0-2 changelog entry instead if you'd prefer it here.

The related pruning overlays should share one per-file metadata block as required by repository guidance.

Done. Moved the six pruning overlays (3 file-remove + 3 file-search-replace — one logical change) into a single per-file overlay document, overlays/0001-remove-windows-import-libraries.overlay.toml, with one top-level [metadata] block (azl-pruning / inapplicable), auto-loaded via the project-wide overlay-files glob in base/comps/components.toml.
Verified it's a pure reorganization: prepare-sources still applies operations=6, the repacked tarball is byte-identical (same SHA512 2a9018a4…a447e4c), render/update --check-only are clean, and the lock is unchanged (upToDate).
The lone release overlay stays inline — it's a single overlay with a distinct azl-release-management category (no repeated metadata to drift), matching the rubygem-rake / java-25-openjdk layout.
The file-remove overlays drop each Windows-only crate's lib/ import libraries, but their .cargo-checksum.json manifests still listed those paths, leaving 16947 dangling entries across 141 crates. Cargo's directory source verifies every path in the files map and fails with "failed to verify the checksum of <pkg>" when one is missing; unlisted files are ignored, so removing the entries is the correct fix. The crates are target-gated to Windows and are not unpacked on a Linux build today, so this is latent rather than breaking, but it would surface if cargo's download filtering changed or a crate stopped being target-gated.

Removes the Windows-only static import libraries (and their now-dangling checksum references) from the kata-containers vendored-dependencies archive. The real problem these cause is ESRP source scanning (mpgear) recursively decompressing a ~1.6M-member
ar-archive explosion in the SRPM; the crates are all target-gated to Windows and never compiled on Linux.What is removed
File removal — three
file-removeoverlays on the vendor archive (lib/only):**/winapi-*-pc-windows-*/lib/**— legacywinapiimport libraries.**/windows_*_gnu*/lib/**— thewindows_*_{gnu,gnullvm}crates (the big one: eachlibwindows.*.aholds ~21,689 members, vendored per arch/toolchain).**/windows_*_msvc*/lib/**— thewindows_*_msvc.libimport archives.Checksum cleanup — three
file-search-replaceoverlays strip the now-danglinglib/...entries from each affected crate's.cargo-checksum.json(regex'"lib/[^"]*":"[a-f0-9]{64}",', replacement omitted so the match is deleted).All these crates are target-gated (
[target.*-pc-windows-*]/cfg(target_env = ...)), so a Linux build never compiles them (the vendor archive is fully unpacked in%prep, but cargo only verifies manifests for crates it actually builds). Only thelib/archives (and their checksum entries) are dropped — each crate'sCargo.toml/src/skeleton is kept, so cargo's resolve stays intact.The repacked archive is pinned via
origin = { type = "overlay" }; the post-overlay SHA512 (2a9018a4...a447e4c) is filled into thesource-filesentry, the renderedsources, and the lock. The release is bumped to3.26.0-2via theazl_releasecounter (abuild.definesmacro folded into upstream'sReleaseby onespec-set-tagoverlay), matching the repo idiom for manual-release components (rubygem-rake,java-25-openjdk). No manual changelog entry is added — kata's spec isn't%autochangelog.Impact
ar-member count: ~1.6M -> 71 (verified by extracting every remaining.a/.libfrom the repacked tarball and summingar t; the 71 arerustixLinux syscall archives that must stay).lib/refs, 0 invalid JSON afterward).Validation
