With the more fine-grained build package set, different images will use
different build pipelines and each of them will be smaller.
We don't currently cache build pipelines so there is no downside to this. Even
when we start caching the difference between having one build pipeline per
image and one shared one is minimal at scale. This will still benefit users
doing one-off builds on-prem.
Most importantly, this tracks things correctly, making pipelines more
composable without having to maintain a global list of dependencies.
Always include the tools for all the filesystem types in the partition table. There may be
usecases for having additional ones, for instance if the partition table is not known, but
this gives us a minimal baseline.
This includes dosfstools in images that have a vfat partition but did not include the tools.
No longer name the packageSetChains after the package set, but
keep them named after the pipelines. This should be a
non-functional change as dnf-json does not care about what the
chains are called, only that the names are unique.
