Commit context includes fb6ce9d07bc31b844243d60cd874a4a5c5862e3c, ff07ebc3ec2152b5a122db2f72d83e3a9684ca27, 8807a009760de140423705ffed539886da2637b7, 95013b363ff42c3300e312c7ed7c1abe72a7ced5, 7d302c38d1ffa2e2b47180290deaafb031a13002, 87f60f60c681af61b518c1acebb9cb3cbd48895e. (2) CI and Test Stability Improvements in Buildah CI, making tests more robust to variations in cgroups v2 weight calculations and enabling non-blocking integration tests to improve total success reporting. Commits include 16c0bdad5ffec4c27b784ec68fe4b92ac74b5c57 and 7a986ebcfc40bf2f9bd12044a1c6df1cd2bbe195. (3) Process Cleanup and Test Harness Stability: reap stray child processes to prevent orphaned processes in test runs, ensuring a cleaner and more stable test harness. Commit: 27c40b3dbeb46dbcf19f0a18f1066fc2565fab76. (4) Robust hard link handling in tar archive creation (container-libs): fixes for incorrect tar headers with chained TypeLink entries when multiple hard links point to the same inode; ensures only the first encountered hard link maps to the inode and is recorded as the target; tests added. Commits: 1801a4b87c4cbd8a8e765cfed8bb31d85293113d and 99b2ff8db75125e8fa3b5b917d7fc3489d6f806a. (5) Tar archive hard-link handling correctness (storage): fixes tar archive creation to handle multiple hard links correctly; only the first encountered file maps to an inode, preventing tar entries where a hard link targets another hard link and addressing Typeflag==TypeLink with Linkname pointing to a TypeLink entry; includes tests for larger numbers of hard links. Commits: 85d15951f0d9b5bd2a99cbf1d7afbee2c92c3e6f and 8aad48ae2da3f18e4417b14db8a1fb55bb43b185. Overall, these changes improve reproducibility of builds, reliability of tar archive generation, and stability of the test and release pipeline, enabling faster, lower-risk releases and better developer velocity.
