Hi
I understand your concern, actually I have same question. In my understanding, there is no way to distinguish between 1.2.0 and 1.2.1 in crux branch unless you have already memorized the commit when 1.2.0 was just announced as released. Unless you already have the ISO(no matter it’s built by self or fetch it as subscriber), otherwise it’s really hard to build the specific history version as time elapsed.
The components of VyOS during building are either from VyOS development repository or build from subpackages. You can check repository, there is no version control for specific version like 1.2.0 or 1.2.1, it’s only for latest crux branch, so even you restored your commit to the point when 1.2.0 was just released, but the building will fetch the latest package, it’s actually dangerous.
Besides, like building script repository, those repositories for subpackages have no specific version control either, so it’s also impossible to build specific history version by building subpackages.
So in summary, it seems the repository only support to build latest crux version. I understand the community have more important task to complete, and hope it can be resolved in the future.
best regards,
