1# This tests validates the order of generated sections that may contain
2# other sections.
3# When a `volume` section has both `subvolume` and `target` children,
4# `target` must go before `subvolume`. Otherwise, `target` will become
5# a child of the last `subvolume` instead of `volume`, due to the
6# order-sensitive config format.
