Could you elaborate a little more about the state transition failures of oneshots caused by timeouts? Let's say for example the oneshot's up script times out, so the transition fails. From s6-rc's point of view the oneshot is still down. What actually happens to the process running the up script? Is it left running in the background? If yes, is it correct to assume that since s6-rc considers it down, another invocation of the s6-rc -u change command on the same oneshot will spawn another instance of the up script? If not, is it killed, and how? I stumbled upon some unexpected behavior while doing some tests yesterday. I'd like to know if this is by design or unintended. Consider this scenario: 2 longruns s1 and s2 s2 depends on s1 s2 takes less than 1 sec to start and become ready on its own s2 has a timeout-up of 5 secs s1 has a run script containing an artificial delay of 6 secs Test 1: s1 is up and ready s2 is down s6-rc -u change s2 Success. OK. Test 2: s1 is down s2 is down s6-rc -u change s2 s6-rc: fatal: timed out s6-svlisten1: fatal: timed out Timeout failure. Unexpected. I thought timeout-up and timeout-down applied to each atomic service individually, not to the entire dependency chain to bring it up or down.
