PR #64 landed on master and added --genesis-release to build-apt-repo.sh -- the
very script this branch deletes, having absorbed the apt assembly + signing phase
into sbuild-all.pl. A plain merge would either resurrect the shell publisher or
silently drop the OpenEmbedded Genesis release from every apt suite, so the
feature is ported to where apt publication now lives.
sbuild-all.pl --genesis-release <dir>:
- The release is validated once at startup, before any build or publish, with the
same checksum-verify-checksum sequence mockbuild-all.pl uses on the rpm side, so
a release rewritten together with its SHA256SUMS while the verifier runs is
rejected. It must be complete (every supported architecture) and carry debs.
- During assemble_into, each release deb is copied into the codename's pool and the
flat per-version directory and re-checked against the verified checksums. That
happens with the publish lock held, between the pool wipe and apt-ftparchive, so
the bytes that are indexed and signed are the bytes that were verified -- the
separate re-verification pass build-apt-repo.sh ran before indexing has no
window left to cover here.
- Copies are plain copies, never link(): a pool file sharing an inode with the
release would let a write through either path change what the other holds.
- Anything staged under the OpenEmbedded Genesis package name is dropped when the
option is given; the verified release is the only source of those packages.
- XCAT::GenesisRelease is loaded on demand rather than imported at compile time. It
pulls in XCAT::BuildUtils, which needs File::Slurper, and xcat-master-ub does not
carry it: a compile-time import made every apt build -- including the ones that
never pass --genesis-release -- die with "Can't locate File/Slurper.pm".
Also here:
- --publish-lock-wait <seconds> makes the 1800s publish-lock wait settable, so a
caller that would rather fail fast than queue can, and so the lock is testable.
- t/genesis_openembedded_consumer.t: the four APT consumer tests now drive
sbuild-all.pl's real publish path (staging tree, publish lock, atomic swap)
instead of build-apt-repo.sh, including the new flock-based lock behaviour.
- The workflow compiles sbuild-all.pl and BuildUtils.pm instead of shellchecking
the removed script; BUILD.md and genesis-openembedded/README.md document the apt
invocation.
Full suite green on both build hosts: 345 tests on xcat-master-ub (Ubuntu 24.04,
where the APT and RPM consumer tests actually run) and 341 on xcat-master.

The two checksum passes around the verifier read as a duplicated walk; say what
the second one is for. Record which rpm versions reproduce the package identity
verify-release requires, so a build host outside that set is a known question
rather than a guess.
%_buildtime is not an rpm macro: built with it alone and no SOURCE_DATE_EPOCH,
rpm 4.14.3, 4.16.1.3 and 4.19.1.1 all stamped the current time. The build time
and build host the release verifier checks come from SOURCE_DATE_EPOCH with
use_source_date_epoch_as_buildtime, and from _buildhost -- both honoured on
every one of those versions and on rpm 6.0.2, where the package also builds
and verifies unchanged.
