In other words, each time you run in live distro mode, it will be as if Ubuntu has been freshly installed For example, if you ve configured a network card or rearranged the desktop, those changes will be lost There are ways around losing settings on each reboot, but they involve partitioning your hard disk, which, frankly, is as much effort as installing Ubuntu from scratch So there s little to be gained by doing so Performance: Because the data must be read from DVD-ROM, running Ubuntu in live distro mode is a slow and, therefore, frustrating experience It can also be noisy if your DVD-ROM is a model that makes a whirring noise as it spins System: As strange as it sounds, Ubuntu is largely unaware of when it s running in live distro mode.

For example, if you were to follow the instructions in 9, which discuss how to update your system, Ubuntu will attempt to update, even though it s running in live distro mode! Of course, it can t do this, because, as far as it is concerned, the DVD-ROM is the hard disk, and it s therefore impossible to write data to it This can create confusing error messages Root: When running in live distro mode, you re automatically given root-user powers We explain the significance of this in 7, but for the moment, it s enough to know that the root user has unlimited power over the system This means that you could repartition the hard disk, for example, or even wipe the hard disk entirely, all without any password prompt or warning.

This can be useful in certain circumstances you can attempt to rescue a hard disk that s having problems using the live distro mode of the Ubuntu disc But using it for everyday tasks is a huge risk, and the potential for accidental damage is high In short, we would recommend that you use live distro mode sparingly and only to get a taste of what Ubuntu is like If you intend to use Ubuntu for any significant period of time, you should install it to your hard disk..
