# Native task outputs are directly run on the target (host) system after being
# built. Even if the output of this recipe doesn't change, a change in one of
# its dependencies may cause a change in the output it generates (e.g. rpm
# output depends on the output of its dependent zstd library).
#
# This can cause poor interactions with hash equivalence, since this recipes
# output-changing dependency is "hidden" and downstream task only see that this
# recipe has the same outhash and therefore is equivalent. This can result in
# different output in different cases.
#
# To resolve this, unhide the output-changing dependency by adding its unihash
# to this tasks outhash calculation. Unfortunately, don't know specifically
# know which dependencies are output-changing, so we have to add all of them.
