You don’t have to reboot after updating Debian (and most mutable distros I think?) packages, you just need to restart the updated software/software using updated libraries.
The easiest way to achieve this is of course to reboot, but it’s not required at all.




















It’s indeed not enforced here, but on top of that the police would really like to know that you have cameras filming public space.
Not so they can do something about it, but so they know they can come to you to ask for footage if something happens.
