brent Always noticed it, never knew.
Even more of a mystery today. Upgrading here was preceded by the "Safety switch ..." notification, yet there was no need to confirm for any of the machines here.
Another mystery is with a bunch of computers here all running the same DE, sometimes some of them require confirmation and others don't, during the same upgrade session.
Like I said, it's so little trouble to simply press 'y'+Enter, it's not worth any worry. Just curious, that's all.
