If the exit-on-idle logic doesn't take outstanding policykit requests into account that's a bug and should be fixed.

We have a define HOME_SLOW_BUS_CALL_TIMEOUT_USEC which is what we use for "slow" bus calls, typically, instead of of the default of 25s. We use it wherever we expect "slow" method calls, because of interactivity and such. It's used in a bunch of places, but likely not at enough.

It really ought not to do > that. I've looked at this more closely now, and it's a bit more complicated than I would have liked. While hostnamed's own idle timeout can easily be disabled while a polkit conversation is in progress, that won't necessarily help anybody using hostnamectl. hostnamectl uses sd-bus's default method call timeout, which is 25 seconds. Perhaps this should be increased for method calls that are likely to result in using polkit? 25 seconds might be too short for some people to enter their password. Is it possible for sd_bus_call to detect that the recipient of a call has dropped off the bus and is never going to return a response? If that were possible we could possibly rely on that rather than an explicit timeout. I think the answer to this question might be "no" though...

It's the other way around. hostnamed uses polkit to authorise requests sent to it over D-Bus. If hostnamed is exiting while in the middle of a polkit conversation, then yes I would say that is a bug in hostnamed. It really ought not to do that.
