Result of your changes

When you start your computer with your own SystemRescueCd version, you can see all the files in /mnt/cloop. If your new files belong to a standard directory, you can access it without a problem. If you made a new directory in the root of the filesystem, it will appear in /mnt/cloop, but you won't see that in the root of the system. In fact, the root of the system contains symbolic links to /mnt/cloop. You may have to make the link yourself.
