there are pros and cons for homeusers this is right in a production environment it is better to control this test and rollout updates automatically at business time and crontrolled restarts in the night where you can decide which depending services on a concrete machine should be stopped before as example you can restart mysqld, having a postfix rely on mysqld running and restart mysqld has negative side-effects you can avoid by a simple script (stop all depedning services, restart mysqld, start all depending services) in my opinion a configuration-file in /etc/sysconfig to control this behavior which is per default active would satisfy all users and administrators, so you have the current behavior as default but give administrators the ability to control like they need
