This is a quick Ansible Playbook that I wrote to update my Debian/Ubuntu based VPS boxes out on the internet. I was tired of having to login and update things or make sure they rebooted even though I have them set to "auto update". Sometimes that wasn't working... I blame the administrator (me)...
It logs into your servers after asking for the sudo password for the user, updates that apt cache then runs the update and upgrade functions. After that completes, it checks for the file that screams if a reboot is necessary. If found, it processes a clean reboot proceedure.
Add support for RPM based systems as soon as I have some that I'm using for daily driving.
