Hurray comrades! CentOS 5.5 released

The Linux release of the CentOS 5.5 distribution, based on the Red Hat Enterprise Linux 5.5 package base, is presented today.

CentOS 5.5 inherits all improvements introduced in RHEL 5.5. A full list of them can be found in the news about the release of RHEL 5.5. Briefly recall the most interesting moments:
Improved hardware support. Updated drivers for a number of wired (vxge, be2net, enic, qlge, tg3, igb, ixgbe, e1000, netxen, bnx2x, bnx2, bnx2i, r8169) and wireless (iwlwifi, rt2x00, ath9k) network cards, storage controllers (iwlwifi, rt2x00, ath9k) network cards, storage device controllers (iwlwifi, rt2x00, ath9k) network cards, storage controllers (iwlwifi, rt2x00, ath9k) network cards, storage controllers (wireless (iwlwifi, rt2x00, ath9k), controllers of storage devices (iwlwifi, rt2x00, ath9k), storage card controllers (iwlwifi, rt2x00, ath9k) hptiop, lpfc, mpt2sas, mptque, megaraid_sas). Implemented support for new platforms and processors. Updated ALSA.
-Improve virtualization tools. The support of hardware technologies for forwarding PCI devices to guest environments (Intel VT-d and AMD IOMMU) has been improved. In libvirt, guest access control to HugeTLBfs is implemented.
Improved installer (anaconda). A number of bugs fixed, support for new storage devices added.
-Expanded support for SystemTap. Added new trace calls (tracepoints), it is possible to start from under a non-privileged user account.
Significantly increased the efficiency of the CFQ I / O scheduler.

')
Compared with the previous version added 8 new packages: freeradius2. gpxe, gsl, postgresql84, python-dmidecode, samba3x, tunctl, xz.
Compared with the previous version updated 188 packages;
In the 54 packages shipped in RHEL 5.5, improvements from CentOS developers were added. For example: anaconda, bluez-utils, eclipse, firefox, gdm, gnome, kde, httpd, thunderbird, yum, etc. In contrast to RHEL, the x86_64 distribution package also includes the 32-bit perl.i386 assembly;

Known issues:

* Due to the increase in the size of executable files, the language packs for OpenOffice.org for the x86_64 architecture had to be transferred to an additional, second disk, therefore, for a full installation, it is no longer enough just to mount the DVD locally (mount -o loop)) and run the installer, after such installation will need to separately install language packs.
* When installing from a local drive, such as a CD or DVD, selecting an extra repository (“CentOS extras repository”) causes the installation process to fail.
* There are problems with the update if there is a proprietary video driver for NVidia cards installed in the systems - after restarting the X server stops running. As a workaround, it is proposed to activate the open source driver “nv” by running system-config-display, and then uninstall and reinstall the proprietary driver.
* Similar to the previous item, reinstalling the driver is required for the x86_64 architecture and for systems where VirtualBox 3.1.6 is installed, otherwise a crash occurs during boot.
