TIP
To do this on a larger scale, you can install a basic openSUSE Linux system into the
Xen virtual machine. Pick a file system, don??™t install the graphical end, and you have
another playground apart from your working system. See the Xen section of Chapter
11, ???Going Cross-Platform,??? for details.
Creating a File System for Testing
People who run Linux tend to be a tinkerer??™s lot. They like to try new things and are not
afraid of getting under the hood and plumbing the depths of their computers to see what
exactly is going on. Although many Linux users have multiple machines (and parts of
machines) cluttering up the house, most people have just one computer with a single
hard drive to play with. If you then have data on that computer that is really important,
you don??™t want to blow away your operating system on a regular basis after an experiment
goes awry. This is perhaps the reason the loopback file system was born. With this
handy tool, you can create an image file containing the file system of your choice, and
mount it??”leaving your real file system alone and safe.
