Installed fast on my 16-inch MBP M1 Max, it usually takes 15-20 min.
In any case, lots of small minor glitches after rebooting, like dock icons have reset to default (ie. all the Apple apps you see on a fresh install, all the stuff I don't use too), and sound output reset to internal speakers when I have headphones plugged in. As mentioned, this is minor stuff, but some configs were apparently wiped.
