Chapter 9. Package And Driver Changes

The list of included packages and system drivers undergoes regular changes in Red Hat Enterprise Linux releases. This is done for a number of reasons: packages and drivers are added or updated in the operating system to provide new functionality, or the packages and drivers may represent out-of-date hardware and are removed. The upstream project for the packages and drivers might no longer be maintained, or hardware-specific packages and drivers are no longer supported by a hardware vendor and are removed.
This chapter lists the new and updated packages and drivers in Red Hat Enterprise Linux 6, as well as those that have been deprecated and discontinued (removed).

9.1. System Configuration Tools Changes

system-config-bind
The system-config-bind tool has been deprecated and removed without replacement. Editing the name server configuration manually via the named.conf file is recommended in Red Hat Enterprise Linux 6. Comprehensive BIND documentation is installed as part of the bind package in /usr/share/doc/bind-x.y.z. Also, sample configurations can be found in the /usr/share/doc/bind-x.y.z/sample directory. The system-config-bind tool from previous versions does, however, generate standard BIND configuration, so depending on your environment it is possible to migrate to the version of BIND found in Red Hat Enterprise Linux 6 by moving old configuration files to the correct location and performing sufficient testing.
system-config-boot
The system-config-boot tool allowed graphical configuration of the GRUB bootloader. In Red Hat Enterprise Linux 6 it has been deprecated and removed without replacement. The default GRUB configuration is sufficient for many users, however if manual changes are required, the boot configuration can be accessed and changed in the grub.conf file, located in the /boot/grub directory. Full documentation for configuring GRUB can be found at the GRUB homepage: https://www.gnu.org/software/grub/.
system-config-cluster
The system-config-cluster tool has been deprecated and removed without replacement. Using ricci and luci (from the Conga project) is recommended.
system-config-display
The system-config-display tool has been replaced by XRandr configuration tools as found in both supported desktops: GNOME and KDE. There is no explicit configuration file (xorg.conf) in the default X server installation as display management is now done dynamically via one of the following menu options:
GNOME: System -> Preferences -> Display
KDE: System Settings -> Computer Administration -> Display
Note: The command line utility (xrandr) can be also used for display configuration. See the xrandr --help command or the manual page via the man xrandr command for further details.
system-config-httpd
The system-config-httpd tool has been deprecated and removed without replacement. Users should configure web servers manually. Configuration can be done in the /etc/httpd directory. The main configuration file is located at /etc/httpd/conf/httpd.conf. This file is well documented with detailed comments in the file for most server configurations; however if required, the complete Apache web server documentation is shipped in the httpd-manual package.
system-config-lvm
The system-config-lvm tool has been deprecated. Users should perform management of logical volumes via the gnome-disk-util or the lvm tools.
system-config-netboot
The system-config-netboot tool has been deprecated and removed without replacement. Using Red Hat Satellite is recommended.
system-config-network
The system-config-network tool has been replaced by NetworkManager - a modern and powerful network configuration tool. NetworkManager-applet (nm-applet) is installed by default in both supported desktop environments and can be found in the system tray panel area. See the NetworkManager home page for further information: https://projects.gnome.org/NetworkManager/.
system-config-nfs
The system-config-nfs tool has been deprecated and removed without replacement. Users should set up NFS server configuration manually.
system-config-rootpassword
The system-config-rootpassword tool has been replaced by the system-config-users tool - a powerful user management and configuration tool. The root password can be set in the system-config-users tool by unchecking the "Hide system users and groups" option in the Preferences dialog. The root user will now be shown in the main listing, and the password can be modified like any other user.
system-config-samba
The system-config-samba tool has been deprecated and removed without replacement. Users should set up SMB server configuration manually.
system-config-securitylevel
The system-config-securitylevel tool has been obsoleted by the system-config-firewall tool.
system-config-soundcard
The system-config-soundcard tool has been removed. Sound card detection and configuration is done automatically.
system-config-switchmail
The system-config-switchmail tool has been deprecated and removed without replacement. Postfix is the preferred and default MTA (Mail Transfer Agent) in Red Hat Enterprise Linux 6. If you are using another MTA, it should be configured manually according to its specific configuration files and techniques.
