Subject: [PATCH] Suppress sync/fsfreeze if not running on a live system
It's possible for e.g. `kernel` to be installed as an RPM BuildRequires or equivalent,
and there's no reason to sync, and *definitely* no reason to fsfreeze.
Another case where this happens is rpm-ostree, which performs its own sync/fsfreeze
globally. See e.g. https://github.com/ostreedev/ostree/commit/8642ef5ab3fec3ac8eb8f193054852f83a8bc4d0
