os-version is a unique key in the index today, but does it need to be?
You could have multiple os-version entries differing only by at least
the following fields:
. revision
. arch
. format
So your unique key internally in virt-builder would be (os-version,
revision, arch, format) ...
Sure, changing the key is not actually an issue by itself; the issue
comes up whether we want the "new" indexes to be usable by older
virt-builders, which want os-version as unique key.
OTOH, if we switch to the virt-builder.d/*.conf configuration files,
those would need to be written anew, so could automatically gain new
features incompatible with older virt-builders.
