1. Installation
Red Hat Enterprise Linux 5.5 introduces many bugfixes and enhancements to the system installer (anaconda).
The interactive installer has been enhanced, adding the abilty to specify additional Network File System (NFS) mount options when installing from an NFS source (BZ#493052). Additionally, install sources (e.g. kickstart files) located on password protected File Transport Protocol (FTP) servers can now be retrieved during installation (BZ#505424).
Kickstart
Kickstart provides a way for users to automate a Red Hat Enterprise Linux installation. Using kickstart, a system administrator can create a single file containing the answers to all the questions that would normally be asked during a typical installation.
Kickstart debugging and error reporting has been improved. The installer now retains kickstart scriptlets during debugging, logs standard output (
stdout) and standard error (stderr) streams, and logs error messages to anaconda.log (BZ#510636).
Package groups can now be excluded in a kickstart installation in the same manner that individual packages are excluded (BZ#558516). Additionally, the
bootloader command now supports the --hvargs parameter, allowing Xen hypervisor arguments to be specified during a kickstart installation (BZ#501438).
Previously, the kickstart installation method offered two options to select all packages
@Everything and * (wildcard). As of Red Hat Enterprise Linux 5.5, both of these options have been deprecated. Attempting to use a select all packages option will fail, unless the kickstart file also includes package negation for conflicting packages. Therefore, to install all packages but conflicting packages, the kickstart file must contain:
%packages @Everything -@Conflicts
Red Hat Enterprise Linux 5.5 includes the new package sets samba3x, freeradius2, postgres84. These package sets are only available via kickstart during system installation or through yum for existing systems.
Hardware Support
The following device drivers are now supported during installation:
