# This tests validates the order of generated sections that may contain
|
|
# other sections.
|
|
# When a `volume` section has both `subvolume` and `target` children,
|
|
# `target` must go before `subvolume`. Otherwise, `target` will become
|
|
# a child of the last `subvolume` instead of `volume`, due to the
|
|
# order-sensitive config format.
|
|
#
|
|
# Issue: https://github.com/NixOS/nixpkgs/issues/195660
