Ubuntu 12.04 on Amazon EC2: /dev/xvda1 will be checked for errors at next reboot

*** /dev/xvda1 will be checked for errors at next reboot ***

It is a bug on Ubuntu 11.04 and 12.04 … which causes a file to be created with a future time stamp that contains that message.

The simplest solution to fix this bug is to delete the notification file:

sudo rm /var/lib/update-notifier/fsck-at-reboot
