I'd also note that this has always been configurable, it is just now suggesting a different value from the default.
I would also suggest that if you're shutting down/rebooting a server, then you really want that to be done sooner rather than later, so stuff getting killed as it shuts down if it doesn't do it normally after SIGTERM is probably fine, because they're likely hung.
Waiting a half hour for a system to reboot is not acceptable.
Indeed, but it is not acceptable because the configuration of the timeout is too long, but because there is probably something earnestly going wrong. And as a server admin, I would like to decide myself to wait patiently and hope, to evaluate the issue, or to pull the plug. I don't want to leave that to a stupid timeout.
15 or 30 seconds is probably fine, even for servers, because of the nature of how systemd processes this timeout. It's per service being shut down, rather than a global timeout.
Yeah, *probably* fine, maybe not. We don’t know, just guess. And as the saying goes: better safe than sorry.
And the 2 mins are empirically obviously a safe solution.
Is it? If the end result is the same, it doesn't matter whether it's 30 seconds or 2 minutes.
Yes indeed. But it’s the sysadmin who decides to reset after those "15 or 30" secs. And that makes a difference.
And mind you, it is not the common case that a standalone server with maybe a few VMs and a moderate workload needs those 10 minutes quoted here for shutdown. It is the exception and an urgent reason to take a serious look not at the 10 mins but at the server.
For desktops, it's probably a different tradeoff.
