Steps to reproduce:
1. Start an Ubuntu 11.10 Oneiric instance on EC2.
Example: ec2run ami-bbf539d2 -t t1.micro -k key
2. Save sudo lsof for reference.
3. apt-cache show upstart
The stock version of upstart installed is 1.3-0ubuntu10.
4. sudo apt-get update; sudo apt-get install upstart
upstart is upgraded to 1.3-0ubuntu11
5. Verify that /var/run/init.upgraded is in fact touched by the install.
6. Save sudo lsof for reference.
7. sudo shutdown -h now
The console displays while unmounting:
mount: / is busy

This causes filesystem recovery errors on next boot.

The post-upgrade lsof is attached.
