Chapter 2. Installation

• The --ignoreDeps and --resolveDeps arguments have been removed. Anaconda

automatically resolves dependencies, but will skip installation of packages that have unmet

dependencies.

• If you want to get the exact same set of packages via Kickstart that you would in a default GUI

install accepting all of the defaults, add the following:

%packages --defaultPackages

%end

• You can also optionally specify the arcitecture of packages that you want installed for multi-arch

installs. For instance:

%packages

glibc.i686

%end

This would add the x86 glibc package to the set, which can be handy on an x86-64 system that

requires the x86 packages for compatibility reasons.

• It is not possible to audit and migrate all of the packages and groups in the %packages section.

Some packages and groups have been removed, some added, and some have had their name

changed. Please refer to the Release Notes for more details.

2.2.2.4. Script Changes

These changes affect the use of %pre, %post and %traceback scripts.

• Logging of errors while running scripts has been improved. Scripts are no longer removed after they

are run, so they can be inspected. This is most useful on systems where the scripts are dynamically

generated so you can see what was run. In addition, the stderr and stdout output is always logged

for every script. This has one important side effect: if your scripts use an interactive program, you

must pass --logfile=/dev/tty3 to the header of your scripts. Otherwise, you will not be able to

interact with the program.

2.2.2.5. Syntax Changes

Changes to the core Kickstart syntax are quite rare. However, there are two important syntax changes

to be aware of:

• The %include option can now accept a URL as an argument, in addition to a file name.

• The %packages, %post, %pre and %traceback sections should now have an %end option at

the end. Previously, these sections had no explicit ending token, but ended where another began.

Starting in Red Hat Enterprise Linux 6, using %end is recommended (and in future releases will be

required). At that point, files without an %end token will fail. Please begin adding this to files as soon

as possible to prevent problems in the future.
