Find details in /usr/src/linux/Documentation/ia64/serial.txt, which is part of the
kernel-source software package.
10.3.4 LD_ASSUME_KERNEL Environment
Variable
Do not set the LD_ASSUME_KERNEL environment variable any longer. In the past,
it was possible to use it to enforce LinuxThreads support, which was dropped. If you
set LD_ASSUME_KERNEL=2.4.x in SUSE Linux Enterprise 10, everything breaks
because ld.so looks for glibc and related tools in a path that does not exist.
10.3.5 Stricter tar Syntax
The tar usage syntax is stricter now. The tar options must come before the file or
directory specifications. Appending options, like --atime-preserve or
--numeric-owner, after the file or directory specification makes tar fail. Check
your backup scripts. Commands such as the following no longer work:
tar czf etc.tar.gz /etc --atime-preserve
See the tar info pages for more information.
10.3.6 Apache 2 Replaced with Apache 2.2
The Apache Web server (version 2) has been replaced with version 2.2. For Apache
version 2.2, Chapter 40, The Apache HTTP Server (page 737) was completely reworked.
In addition, find generic upgrade information at
http://httpd.apache.org/
and the description of new features at
docs/2.2/upgrading.html http://
httpd.apache.org/docs/2.2/new_features_2_2.html.
10.3.7 Kerberos for Network Authentication
Kerberos is the default for network authentication instead of heimdal. Converting
an existing heimdal configuration automatically is not possible. During a system update,
backup copies of configuration files are created as shown in Table 10.1, "Backup Files"
(page 214).
