Hurray comrades! CentOS 5.5 released


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

    CentOS 5.5 inherits all the improvements introduced in RHEL 5.5. A complete list of them can be found in the news about the release of RHEL 5.5. Briefly recall the most interesting points:
    -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 device controllers, (qla2xx hptiop, lpfc, mpt2sas, mptque, megaraid_sas). Implemented support for new platforms and processors. Updated ALSA.
    -Improvements in virtualization. Support for hardware technologies for transferring PCI devices to guest environments (Intel VT-d and AMD IOMMU) has been improved. Libvirt implements guest access control for HugeTLBfs.
    -Improved installer (anaconda). A number of bugs were fixed, support for new storage devices was added.
    -Expanded support for SystemTap. New tracepoints have been added; launching from under an unprivileged user account is possible.
    Significantly increased CFQ I / O Scheduler performance.
    -New Samba with improved support for new versions of Windows (2008, Vista, 7) and the ability to deploy clusters.
    -Added packages for PostgreSQL 8.4 and FreeRADIUS 2.

    Plus information from the website :

    Compared to the previous version, 8 new packages have been added: freeradius2. gpxe, gsl, postgresql84, python-dmidecode, samba3x, tunctl, xz.
    Compared to the previous version, 188 packages have been updated;
    The 54 packages shipped in RHEL 5.5 have been enhanced by CentOS developers. For example: anaconda, bluez-utils, eclipse, firefox, gdm, gnome, kde, httpd, thunderbird, yum, etc. Unlike RHEL, the x86_64 distribution package also includes a 32-bit perl.i386 build;

    Known Issues:

    * Due to the increase in the size of executable files, the language packages for for the x86_64 architecture had to be transferred to an additional second disk, so now for a full installation it is no longer enough just to mount the DVD locally (mount -o loop) and run the installer, after this Installation will need to separately install the language packs.
    * When installing from a local drive, such as a CD or DVD, selecting an extra repository (“CentOS extras repository”) will cause the installation to fail.
    * There are problems during the update if there is a proprietary video driver for NVidia cards installed in the systems - after rebooting, the X-server stops starting. As a workaround, it is suggested that you activate the open "nv" driver by running system-config-display, and then uninstall and reinstall the proprietary driver.
    * A reinstallation of the driver similar to the previous point is required for the x86_64 architecture and for systems on which VirtualBox 3.1.6 is installed, otherwise a crash is observed during boot.
