Hello, just to confirm that I still diff for zvariant package , I tested
with the followin setup on poky master:
local;conf:
SANITY_TESTED_DISTROS = ""
OEQA_REPRODUCIBLE_TEST_TARGET = "zvariant"
OEQA_REPRODUCIBLE_TEST_SSTATE_TARGETS = "rust-native cargo-native"
and
OEQA_DEBUGGING_SAVED_OUTPUT=/home/jenkins/yocto-poky-master/reproducible_saved_output
oe-selftest -r reproducible.ReproducibleTests.test_reproducible_builds
