# End-to-end regression tests for smoke-boot.sh. Each case launches a fake
# "service" through smoke-boot.sh and checks its verdict from the exit code --
# smoke-boot no longer scans logs, so its decision is driven purely by whether
# the process reaches LISTEN, exits, or hangs.
#
# Guards issue #6332: a service that boots fine but prints exception-name prose
# in its log (e.g. jOOQ's random "tip of the day") must PASS; and a service that
# crashes on boot must still FAIL.
