Updating the System and Package Management

5.1.4 Manual Update

Updating the Base System

As basic system components, such as libraries, must be exchanged when

updating a base system, an update cannot be run from within a currently

running Linux system. First, set up the update environment. This is nor-

mally done using the CD or DVD or with a custom boot disk. If you are

carrying out manual modiﬁcations during the update or prefer to perform

the entire update with YaST in text mode, follow the steps described in Sec-

tion 3.3 on page 125. Below is a summary of this procedure.

1. Immediately after booting the kernel from the boot disk or from the

CD or DVD, linuxrc automatically starts.

2. In linuxrc, specify the language and keyboard settings under ‘Set-

tings’ and click ‘OK’ to conﬁrm each setting.

3. You might need to load the required hardware and software drivers

via ‘Kernel Modules’. See Section 3.1 on page 114 for more details

of how to proceed and Section 3.1.3 on page 117 for a description of

linuxrc.

4. Go to ‘Start Installation or System’ ➝ ‘Start Installation or Update’ to

select the source medium (see Section 3.1.5 on page 119).

5. The installation environment is loaded from linuxrc then YaST starts.

Following the selection of a language and the hardware detection by YaST,

select ‘Update Existing System’ in the YaST opening screen. Next, YaST

attempts to determine the root partition and displays the result for se-

lection or conﬁrmation. Select your root partition from the list (example:

/dev/hda2). In this way, prompt YaST to read the old fstab from this par-

tition. YaST analyzes and mounts the ﬁle systems listed there.

Then you have the possibility to make a backup copy of the system ﬁles

during the update. In the following dialog, either choose to update only the

software already installed or to add important new software components to

the system (upgrade mode). It is advisable to accept the suggested composi-

tion (e.g., ‘Standard system’). Adjustments can be made later with YaST.
