both applications and kernel upgrades can request that a reboot occur. It is rarer for applications (in general) to request this, however, some core system apps may require this in order to continue proper operation and avoid data corruption/crashes from occurring if you do not reboot.
A core app cannot always be restarted without a full reboot, while most other apps can simply be restarted. It is only in this circumstance (where is can only run after reboot) that a reboot would be required from a system app. -- Kubuntu Restart Notification Balloon Should not Repeatedly show up https://bugs.launchpad.net/bugs/271419 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
