# Make python flush messages instead of buffering.
# When reading the systemd journal, we need to see the messages
# in the exact order. There will suddenly be a lot of messages
# from naxalnet, networkd, iwd and resolved. When buffering is on,
# we won't see the messages from naxalnet in the order they were
# printed. This, among other problems, make it hard while debugging.
# This will no longer be needed when naxalnet sends its messages
# directly to the systtemd journal instead of stdout.
