In Mountain Lion I was able to permanently disable Notification Center, with no apparent side effects:
launchctl unload -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist killall NotificationCenter
However, the Mavericks upgrade process restored Notification Center in all its irritating glory. Is there are reason that the upgrade reverted my disabling of Notification Center?
Can I disable Notification Center in Mavericks using the same procedure, without side effects?
