A riscv64 goconserver `go build` sat 26 minutes with zero CPU ticks across a
20-second sample, both Go pids in futex_wait and no socket open. Nothing bounds
a build step, so the cell did not fail -- it hung, and a hung run reads as
"still running" rather than as a defect.
t/build_timeout.t drives the bounded path with a command that hangs and asserts
that the call returns, reports a timeout, and prints the process tree, each
pid's wchan, the open socket count and a CPU-tick sample. A second case drives a
spinning command and asserts the report calls it slow, not deadlocked, so the
sample means something.
Each call under test runs in a forked child whose stdio is detached to a file,
and the parent bounds that child. An unbounded run must fail this test, not
block prove.

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.
