Public bug reported:
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.
