I learnt it the hard way. I had an ubuntu ec2 instance where I added a line to mount an ebs instance. I didn’t know what nobootwait does and I just went with defaults. I don’t exactly recall what happened, but the /dev/whatever I had in /etc/fstab wasn’t found when I rebooted the instance, and ubuntu helpfully stuck to the “manually mount or skip” screen. Except that there is no way to do that while you are booting an ec2 instance.
