# BRINTOS-WORKAROUND: brintos/linux#19 remove -- oe-core's run-ptest is
#
#     su -c ./test.sh ptest
#
# and on this arm that never reaches test.sh. The wasm32 syscall table wires no
# credential setter (setuid/setgid/setgroups/setres*/setfs* are all NULL rows ->
# -ENOSYS, while the getters are wired), so su dies with "Function not
# implemented" before test.sh is reached -- at initgroups while /bin/su was the
# busybox applet, and at setgid since shadow's port took the name through
# update-alternatives. ptest-runner then reports
# TOTAL: 1 FAIL: 1 with not one of the 62 tests run -- and, because upstream's
# test.sh writes nothing before the drop, the transcript is indistinguishable
# from a suite that ran and passed nothing.
#
# The drop is ptest CONVENTION, not something quilt's tests need: each one works
# in a private directory the invoking user already owns, and none asserts a
# permission failure that root would defeat. So this copy runs the suite
# directly. It still ATTEMPTS the drop first, so the day #19 lands the suite goes
# back to running unprivileged with no edit here, and 53-quilt.test asserts the
# gap separately and inverted (quilt/su-setgroups-enosys) so the case turns red
# then -- which is the signal to delete this file and let poky's own run-ptest
# win again.
