The the problem with the unix implementation is that the processes that remain running do not get the update. So if you have a package that contains some critical fix (say for a security issue) then it is not applied until app restarts. Of course, this is easy enough to script. The smart thing about the unix model is that you have a choice up-front which apps on the system need to go down, and when.
It's good to see some progress in this area from Microsoft. The current frequency of reboots caused by patching is unacceptable, and having the ability to easily find out what needs to be restarted is going to be useful.
