# In the corresponding nix file, we have two derivations: the first, named root,
|
|
|
|
|
# is a normal recursive derivation, while the second, named dependent, has the
|
|
|
|
|
# new outputHashMode "text". Note that in "dependent", we don't refer to the
|
|
|
|
|
# build output of root, but only to the path of the drv file. For this reason,
|
|
|
|
|
# we only need to:
|
|
|
|
|
#
|
|
|
|
|
# - instantiate the root derivation
|
|
|
|
|
# - build the dependent derivation
|
|
|
|
|
# - check that the path of the output coincides with that of the original derivation
