Bug Description
Problem:
To upgrade the Operating System, including any applications, takes too less time.
On a modern PC (Core 2 Duo, 2.3 Ghz, 2 GB RAM) the entire process takes about 31 minutes. (Excluded time for downloading files, running from a local mirror). On a slower system it might take still an hour or so, but that is still much to fast.
Use case:
Tim starts a company in System Administration. He installed Ubuntu 7.10 about 5 months ago in a company with 4 computers. In April 2008, he announces that all computers need to be upgraded. The owner of the company schedules a special day off for all employees, because of the expected downtime.
Tim takes the repositories with him on an external usb drive. He makes that drive available to the network. He starts the upgrade process and roughly 2.5 hours later he is finished with this major update.
Consequences:
Tim looses his contract with the client, because they accuse him of fraud. They can not believe that their system was upgraded in less then 3 hours. They revert to another operating system and hire someone who spends 4 days upgrading 4 computers.
Repeatability:
1. Install Ubuntu 7.10.
2. Upgrade to 8.04.
Possible Solution:
Make the upgrade process slower by inserting random wait() loops. Make it impossible to run an upgrade on a running system. Make it mandatory to backup all data, wipe the harddisk, re install the OS, and then restore the data. Make sure all applications that don't come with the OS, need a complete reinstall. Make sure that user directories and preferences get lost dring the upgrade; but make a handy tool to import the User Settings from the previous installation.
