We don't currently want the minimal-plus target to be user-facing. It's
intended only for other Fedora variants.
Let's support "hidden" manifests by having their names end in
`.hidden.yaml`. Then, make `minimal-plus` hidden.
I considered instead having them start with `.` to match
well-established semantics, but I don't like either that this hides them
from an `ls` in the git repo (or even with `-a`, puts them higher up
whereas I want it to be close to `minimal.yaml`).
I also considered leveraging the existing symlink hiding semantics, but
it also felt awkward to rename a file and add a symlink to it just for
the purpose of hiding it.
It's confusing right now how the manifest names differ across
fedora-bootc, centos-bootc and rhel-bootc. Both rhel-bootc and
centos-bootc only use "bare" names like `minimal`, and `standard`, while
fedora-bootc prefixes everything with `fedora-`.
For FCOS/SCOS/RHCOS, it would be beneficial to maintain the same naming
across all of those.
Let's just match the naming here to the "bare" version. But add symlinks
so that we don't break the old names (but note that being symlinks, they
will no longer show up in `bootc-base-imagectl list`).
An update of a compose image from a specific Fedora version
triggers at least 4 builds: 'minimal', 'minimal-plus', 'standard'
and 'iot'.
We usually have 2 compose images updates (Fedora 42 and Rawhide) per
day so up to 8 builds are triggered at the same time. As we don't seem
to have a lot of resources in the Konflux cluster this leads to
build failures because of timeouts (the default pipeline timeout is 1h).
This change tries to mitigate this until we get more resources in the
Konflux cluster.
