Chapter 3. Rescue Mode
When things go wrong, there are ways to fix problems. However, these methods require that you understand the system well. This chapter will describe the ways that you can boot into rescue mode and single user mode, where you can use your own knowledge to repair the system.
What is Rescue Mode?
Rescue mode provides the ability to boot a small Linux environment entirely from a diskette, CD-ROM, or using some other method.
As the name implies, rescue mode is provided to rescue you from something. During normal operation, your Red Hat Linux system uses files located on your system's hard drive to do everything — run programs, store your files, and more.
However, there may be times when you are unable to get Linux running completely enough to access its files on your system's hard drive. Using rescue mode, you can access the files stored on your system's hard drive, even if you cannot actually run Linux from that hard drive.
Normally, you will need to get into rescue mode for one of two reasons:
You are unable to boot Linux.
You are having hardware or software problems, and you want to get a few important files off your system's hard drive.
