In the warning dialog, select ‘Yes’ to start the installation of the new soft-

ware from the source medium to the system hard disk. First, the RPM

database is checked, then the main system components are updated. YaST

automatically creates backups of ﬁles modiﬁed in the running system since

the last installation. In addition, old conﬁguration ﬁles are backed up with

the endings .rpmorig and .rpmsave. The installation or update proce-

dure is logged in /var/log/YaST2/y2log* and can be viewed later at

any time.

Updating the Rest of the System

After the base system is updated, you are switched to YaST’s update mode.

This mode allows you to tailor the rest of the system update to your needs.

Complete the procedure as you would a new installation. Among other

things, select a new kernel. The available options are presented by YaST.

Possible Problems

If certain shell environments no longer behave as expected after the update,

check to see if the current dot ﬁles in the home directory are still compati-

ble with your system. If not, use the current versions in /etc/skel. For

example, cp /etc/skel/.profile /.profile.

5.2 Software Changes from Version to

following in detail. This summary indicates, for example, whether basic

settings have been completely reconﬁgured, whether conﬁguration ﬁles

have been moved to other places, or whether common applications have

been signiﬁcantly changed. The modiﬁcations that affect the daily use of

the system at either the user level or the administrator level are mentioned

below.

Upgrading to Kernel 2.6

SUSE LINUX is now based entirely on kernel 2.6. The predecessor ver-

sion 2.4 should no longer be used, as the enclosed applications may not

work with kernel 2.4. Moreover, note the following details:
