Release 6.9 - 2026-10-01

Breaking changes

• Mock now always runs rpmbuild with --noclean (when supported), so the %clean section of spec files is no longer executed. Mock does its own cleanup of the build directory, and keeping the directory around is needed for the separate %check phase. Spec files that rely on their %clean section being performed in a Mock build would need to be adjusted — but we believe no such spec files exist in practice.

New features

• Add a %check test to mock-core-configs that asserts openEuler source repositories use the literal openEuler-<version> directory in metalink ... path= URLs rather than the untranslated $releasever, which the metalink path= form does not expand.

Bugfixes

• Probe if systemd-nspawn has the –restrict-address-families option and use it if available. Otherwise, systemd-nspawn will print a warning about planned changes to its default behaviour in a future version and urge to use said option (issue#1799). This pollutes mock’s output, breaking other tools, like fedora-review (rhbz#2511998).

• Fix separate_check builds with a separate --resultdir. A resultdir outside of the chroot directory enables cleanup_on_success, and that in turn made Mock run rpmbuild without --noclean. The %clean stage then removed the build directory before the separate %check phase could run, so rpmbuild -bk --short-circuit failed with rpmbuild.env: No such file or directory (issue#1808). Mock now always runs rpmbuild with --noclean and does its own cleanup, so the build directory survives for the separate %check phase.

• The unbreq plugin reports fewer false positives. When checking whether all the providers of a BuildRequires can be removed together, the result of the check was ignored and every provider from the previous step was reported as unused. The providers deduplication also checked the length of the BuildRequires name instead of the length of the list of providers

Mock Core Configs changes

• The openSUSE Tumbleweed %dist macro expands to .suse.tw<snapshot> again (it had been expanding to just .suse.tw), and loading the Tumbleweed config no longer prints a Python SyntaxWarning (issue#1785).

• The AlmaLinux Kitten + EPEL 10 configs have been updated to use a new 10s pattern. This is related to a minor reconfiguration of EPEL 10 minor version repo redirects. See this discussion thread for more details.

• Add Amazon Linux 2027 configuration and mark AL2 eol

• Amazon Linux 2023 has a buildsys-build group that is used to set up the chroot now instead of the enumerated package set.

• The CentOS Stream + EPEL 10 configs have been updated to use a new 10s pattern. This is related to a minor reconfiguration of EPEL 10 minor version repo redirects. See this discussion thread for more details.

• Add openSUSE Leap 16.1 configurations (issue#1786). openSUSE Leap 16.1 is currently in beta; the configurations use the same GPG keys as Leap 16.0.
