Add a third migration lane to rechunk-to-chunkah-migration.yaml that tests the target end-state: switching from ublue-os/bluefin (gzip) to a zstd:chunked projectbluefin/bluefin image with unified bootc storage. Changes: - chunked-enabled parameter (default 'true') gates all chunked steps; set to 'false' to disable the lane without touching anything else - chunkah-image-chunked / chunkah-image-tag-chunked parameters point at the local zot (192.168.1.102:5000/bluefin:zstd-chunked) - prepare-chunked-image template: skopeo-copies the chunkah gzip image to local zot with --dest-compress-format=zstd:chunked before any VM provisioning runs - provision-chunked + migration-chunked lanes wired into the matrix, both gated by chunked-enabled; teardown-chunked added to cleanup - Backport tls_flag fix to inspect-image-compression (local HTTP registry needs --tls-verify=false in skopeo inspect) - Backport local registry trust injection to run-bootc-switch: when switching to 192.168.1.102:5000/* injects registries.conf.d entry + policy.json patch and drops --enforce-container-sigpolicy; verifies registry is reachable before attempting the switch Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Wrong repo — zstd:chunked test coverage belongs in projectbluefin/testsuite, not here. Closing. |

What
Adds a third lane to
rechunk-to-chunkah-migration.yamlthat tests the target end-state: migrating fromublue-os/bluefin(gzip) →projectbluefin/bluefinwith zstd:chunked compression + unified bootc storage.Why
The existing two lanes cover gzip (default storage) and gzip (unified storage). This adds the missing zstd:chunked scenario which is the format we expect to ship long-term.
