I think it's a combination of all these: * If you simply apply updates and don't restart everything that uses the things updated you will not be taking advantage of the security or bugfixes. If those things are used by a lot of your apps, restarting each one is tedious and/or as disruptive as just rebooting anyhow. * Even though live updates work 'pretty well' there will always be a number of corner cases where applications will not function correctly after they are updated but before they are restarted. Directories or resources they need may have changed, etc. Running tracer for a while can really open your eyes to how many things need restarting after normal updates flow. One thing that might make this less annoying to people would be ability to schedule the reboot for some off hours time (2am or something) and also ability (for gnome at least) to restore apps/windows/session again on login. kevin
