Possible Problems - Novell LINUX ENTERPRISE SERVER 10 - INSTALLATION AND ADMINISTRATION 08-05-2008 Installation Manual

applies to files stored in /etc as well as some of the directories and files in /var and
/opt. You may also want to write the user data in /home (the HOME directories) to
a backup medium. Back up this data as root. Only root has read permission for all
local files.
Before starting your update, make note of the root partition. The command df / lists
the device name of the root partition. In
the root partition to write down is /dev/hda3 (mounted as //).
Example 10.1 List with df -h
Filesystem
/dev/hda3
tmpfs
/dev/hda5
/dev/hda1

10.1.2 Possible Problems

If you update a default system from the previous version to this version, YaST works
out necessary changes and performs them. Depending on your customizations, some
steps or the entire update procedure may fail and you must resort to copying back your
backup data. Check the following issues before starting the system update.
Checking passwd and group in /etc
Before updating the system, make sure that /etc/passwd and /etc/group do not
contain any syntax errors. For this purpose, start the verification utilities pwck and
grpck as root and eliminate any reported errors.
PostgreSQL
Before updating PostgreSQL (postgres), dump the databases. See the manual page
of pg_dump. This is only necessary if you actually used PostgreSQL prior to your
update.
