摘要
Red Hat Enterprise Linux 更新版是增強功能、安全與修正 bug 後的小幅更新。Red Hat Enterprise Linux 5.5《發行公告》紀錄了 Red Hat Enterprise Linux 5 作業系統與其應用程式的主要變動。關於此更新版本的詳細資料,請參閱《技術公告》。
Red Hat Enterprise Linux 5.5 包括了對 Intel Boxboro-EX 平台、AMD Magny-Cours 處理器與 IBM Power 7 處理器的硬體支援。虛擬化更為精進,支援多張 10 GigE SR-IOV 網路卡,並會自動為虛擬客座端使用 hugepages(若系統上啟動此功能)。異質平台也有所改進,OpenOffice 現在加入了微軟 Office 2007 的篩選器,Samba 與 Windows 7 相容,同時虛擬機器可使用微軟 PXE 服務。
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:
