It’s actually astonishing to me how much better Linux deals with updates compared to macOS and Windows. “Oh, updates are installed, and you just need to restart whatever I updated if it’s currently running.”
Sometimes it does have its moments though, like when it updates some core package and changes its config in such a way that the next boot doesn’t go into a GUI, but I think it’s also fair to point out Windows has had those too. And macOS High Sierra with the performance and security issues it initially had on release won’t go unmentioned by me either.
Personally I don’t actually remember this, I do remember waiting for each individual app to download and install, and slowly watching the progress bar in the notification area, waiting for a new game to download on my Android 4.3 tablet. Ah, memories.
