So, systemd has to for determining the backing file system of some directory
and this is used by gpt-auto-generator for finding the block device
backing / or /usr/. I figure you want something like that?

We don't expose that directly though, and it's limited, since we do
not cover complex storage. We do cover btrfs though.
