Never try to upgrade an existing installation using live-cd

[davidwhodgins]

Just a reminder to ensure everyone is aware, Live cds should NEVER be used to upgrade an existing system.

Live cds should only be used for testing, and for clean installs.

When installing from a live cd, the running system from the live cd is copied to the selected filesystem(s), overwriting anything that is already there, and then customizing the installation for the hardware it's being installed on.

During the first boot of the newly installed system, any files created in the home directory of the live cd, will be copied into the home directory of the first user created, overwriting any existing files that are there.

An example where this has happened. While running a live cd, firefox was run creating the /home/live/.mozilla directory in the live cd filesystem. The installation was done, unselecting the option to format the /home file system. On first boot, the same user name that was used in the prior installation was entered as the first user. The result was that the files in /home/user/.mozilla were overwritten with the copy created while using the live cd.
