Not quite - my plan is that anaconda would substitute `${basearch}` for values passed to
`ostreesetup.ref`, i.e. we'd use:
```
ostreesetup --nogpg --osname=fedora-atomic --remote=fedora-atomic
--url=https://kojipkgs.fedoraproject.org/compose/atomic/$releasever/
--ref=fedora/26/$basearch/atomic-host
```
Having rpm-ostree itself do the substitution would be...well, it hurts my head to think
about. A huge number of things would need to change. Basically the whole codebase
assumes it's not variable based on the booted architecture. I don't know offhand
what even the use of a dynamic substitution there would be.
