The image was a folder, vm/, holding base.qcow2 and what boots it. It is
now one file next to the ISO, with the ISO's name and its own checksum
file, the way Ubuntu, Debian, Arch, Fedora and CentOS publish theirs:
edge/<version>/omarchy-edge-<version>.qcow2
stable/<version>/<run>/omarchy-<version>.qcow2
The image boots by itself through UEFI. What a direct boot needs, the
kernel, initramfs, kernel arguments and vm-boot, is in an unpacked/
folder beside it, Ubuntu's name for the same thing. The firmware
variables are no longer published: a boot with the firmware's defaults
finds the disk.
latest.json follows: vm.url, vm.sha256 and vm.size are the image, as
url, sha256 and size are the ISO; vm.unpacked and vm.unpacked_files are
the folder. vm-boot takes the image file. The publish job compares every
file it uploaded, whatever the layout. README, tests and the workflow's
header say the same.
Which channels a run makes and where they go, and what is laid out and
what latest.json then says, were shell inside the workflow file, tried
only by hand. A green run published a latest.json with the Omarchy
version in it twice, and nothing noticed.
Both are scripts now, test/vm-image/nightly-plan and nightly-layout,
and test/unit/nightly-test.sh tries them without a runner: a first run,
a run started again, a release already published, a tag that is not a
version; every field of latest.json for each channel, the checksums
against the files, the version a consumer reads from the ISO's name.
nightly-layout also refuses to describe an image it cannot describe
fully, and checks its own latest.json before anything is published.
The same test covers two things the install test decides: which Omarchy
packages an ISO installs, and when an install is over.
