I threw in the towel instantly...couldn't see any reason to try a restart, but this was my third or fourth High Sierra clean install, and it's the first time I was asked to enter my password when starting up.
It's actually the first time I've EVER been asked to enter my password when starting up since I set the pref about a million years ago.
Yeah, about 875,000 years ago things changed.
I was asked for my password too, upon restart, but I don't think I am asked every time, but have been in the last 875,000 years. It may have to do with the type of update that is applied. This last one included security updates, so maybe that's the difference this time.
