Scenario

You are remotely changint the network configuration of your server.
If you make a mistake, you will not be able to connect to your server after reboot.

Solution

The script /etc/etckeeper/rollback-reboot shown above reverts the changes in your /etc and performs a reboot, in case you do not kill it in 5 minutes.

Requirements

You must have the following packages installed:

  • initscripts
  • etckeeper

You also must call /etc/etckeeper/rollback-reboot like this in your /etc/rc.local like this:

#!/bin/bash

# it's a good idea to update your dynamic IP as soon as you reboot
/sbin/ddns-update

# ability to rollback changes in /etc and perform a reboot, if necessary
nohup /etc/etckeeper/rollback-reboot &

exit 0
