The rescue system can be loaded from various sources and locations. The simplest
option is to boot the rescue system from the original installation medium:
1 Insert the installation medium into your DVD drive.
2 Reboot the system.
3 At the boot screen, press [F4] and choose DVD-ROM. Then choose Rescue
System from the main menu.
4
Enter root at the Rescue: prompt. A password is not required.
If your hardware setup does not include a DVD drive, you can boot the rescue
system from a network source (including the openSUSE FTP server). The following
example applies to a remote boot scenario—if using another boot medium, such
as a DVD, modify the info le accordingly and boot as you would for a normal in-
stallation.
1 Enter the conguration of your PXE boot setup and add the lines
install=
protocol
://
instsource
and rescue=1. If you need to start the repair
system, use repair=1 instead. As with a normal installation,
protocol
stands
for any of the supported network protocols (NFS, HTTP, FTP, etc.) and
instsource
for the path to your network installation source.
2 Boot the system using “Wake on LAN”, as described in Section “Wake on LAN”
(Chapter 2, Remote Installation, ↑Reference).
3
Enter root at the Rescue: prompt. A password is not required.
Once you have entered the rescue system, you can make use of the virtual consoles
that can be reached with [Alt] + [F1] to [Alt] + [F6].
A shell and many other useful utilities, such as the mount program, are available in
the /bin directory. The sbin directory contains important le and network utilities
for reviewing and repairing the le system. This directory also contains the most
important binaries for system maintenance, such as fdisk, mkfs, mkswap, mount,
mount, init, and shutdown, and ifcong, ip, route, and netstat for maintaining the
network. The directory /usr/bin contains the vi editor, nd, less, and ssh.
To see the system messages, either use the command dmesg or view the le /var/
log/messages.
