To automate the installations of updates on our servers I am experimenting with the package unattended-updates. Good introductions can be found here:
- http://syslog.tv/2012/01/28/automaticunattended-updates-on-debian-6-squeeze/
- http://mb.walter.silvergeeks.com/rechner/automatische-updates-aus-security-in-debian-stable/
- https://help.ubuntu.com/community/AutomaticSecurityUpdates/#Using_the_.22unattended-upgrades.22_package
I have to admit that I am a bit uneasy, but in the past year of applying updates by hand nothing ever broke. So I assume that this should not cause any problems. At least it will cut down the spam flood of nagios notices when updates become available :)
