I wonder if wireless connectivity is related? When I reboot with and without a wired connection attached, I get the same result. But maybe wireless is causing delays just by being configured, even if a wired connection is available?

Is why I'm not trying to focus on individual services beyond understanding what they do or what they need, to see if there's a pattern. My top suspect is network related, because I get the weirdest changes by just changing hostname and rebooting, which is baffling to me.
