One time I accidentally messed with the /etc/passwd and locked myself out of being able to SSH into the machine. Since this is a remote machine in AWS I had no way of doing what I'd normally do. Which is attaching a keyboard and monitor and fixing this manually.

To fix, use the AWS EC2 Management page to:

• spin up a new instance of vanilla ubuntu EC2 (let's call it David)
• shutdown the locked machine (let's call it Goliath)
• unmount Goliath's volume
• attach the volume to David

Then follow this guide: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-using-volumes.html
