Installation-Related Notes

   This section outlines those issues that are related to Anaconda (the Red
   Hat Linux installation program) and installing Red Hat Linux 8.0.92 in
   general.

     o The Red Hat Linux installion program has the ability to test the
       integrity of the installation media. It works with the CD, DVD, hard
       drive ISO, and NFS ISO installation methods. Red Hat recommends that
       you test all installation media before starting the installation
       process, and before reporting any installation-related bugs (many of
       the bugs reported are actually due to improperly-burned CDs). To use
       this test, type linux mediacheck at the boot: prompt.

     o While most present-day computers are able to start the installation
       process by booting directly from the first Red Hat Linux distribution
       CD, some hardware configurations require the use of a boot diskette.
       If your hardware requires a boot diskette, you should be aware of the
       following change.

       Red Hat Linux 8.0.92 uses a different boot diskette layout than
       previous releases of Red Hat Linux. There is now a single boot
       diskette image file (bootdisk.img) that is used to boot all systems
       requiring a boot diskette.

       If you are performing anything other than an installation from an IDE
       or USB device, you will be asked to insert a driver diskette created
       from one of the following image files:

       - drvnet.img - For network installations

       - drvblock.img - For SCSI installations

       - pcmciadd.img - For PCMCIA installations

       As with previous releases of Red Hat Linux, these image files can be
       found in the images/ directory on the first installation CD.

     o The Red Hat Linux 8.0.92 installation program has undergone
       significant changes to its bootstrap process.

       These changes affect the following aspects of the installation:

       - All installation methods (CDROM, NFS, FTP, HTTP, and hard drive)

       - Kickstart file ks.cfg access methods (diskette, CDROM, nfs, http,
       and hard drive)

       - Driver diskette support

       - PCMCIA support

       - Rescue mode

       Please exercise these aspects in your environment as heavily as
       possible and report any issues you may find.

     o The XFree86 configuration code has been restructured; please report
       any video card configuration regressions. Manual override of video ram
       as well as running X without a mouse should work now.

     o The Red Hat Linux installation program now detects existing Red Hat
       products on your system, and will prompt you to indicate which product
       you would like to upgrade. You also will have the option of performing
       a complete reinstallation of the system instead of upgrading. Please
       report any problems you may experience with this new feature.

     o isolinux is now used for booting the Red Hat Linux installation CD. If
       you have problems booting from the CD, you can write the
       images/bootdisk.img image to a diskette according to the directions in
       the Red Hat Linux Installation Guide.

       If you want to make your own CD to boot the installation program, copy
       the isolinux/ directory from the first CD into a temporary directory
       (referred to here as <path-to-workspace>) using the following command:

       cp -r <path-to-cd>/isolinux/ <path-to-workspace>

       Change directory to <path-to-workspace>:

       cd <path-to-workspace>

       Make sure the files you have copied have appropriate permissions:

       chmod u+w isolinux/*

       Finally, issue the following command to create the ISO image file:

       mkisofs -o file.iso -b isolinux.bin -c boot.cat -no-emul-boot
       -boot-load-size 4 -boot-info-table -R -J -v -T isolinux/

       Burn the resulting ISO image (named file.iso and located in
       <path-to-workspace>) to a CD as you normally would.

     o During a graphical installation, you can now press SHIFT-Print Screen
       and a screenshot of the current installation screen will be taken.
       These are stored in the following directory:

       /root/anaconda-screenshots/

       The screenshots can be accessed once the newly-installed system is
       rebooted.

     o The parted disk partition manipulation program has been upgraded to
       version 1.6. Look for misidentification of file system types and
       errors on disks with unusual partition tables.

     o If you are performing a text mode installation, errors may be
       displayed on the console during package installation. This is a known
       problem.

     o Minimal installations currently require more than a single CD.

General Notes

   This section describes post-installation issues.

     o XFree86 3D does not always work. Please report any problems in
       Bugzilla (http://bugzilla.redhat.com/bugzilla/).

     o There have been issues observed when upgrading Red Hat Linux 6.<x>,
       7.<x>, 8.0, and 8.0.92 systems running Ximian GNOME. The issue is
       caused by version overlap between the official Red Hat Linux RPMs and
       the Ximian RPMs. This configuration is not supported by Red Hat. You
       have several choices in resolving this issue:

       1) You may remove Ximian GNOME from your Red Hat Linux system prior to
       upgrading Red Hat Linux.

       2) You may upgrade Red Hat Linux, and then immediately reinstall
       Ximian GNOME.

       3) You may upgrade Red Hat Linux, and then immediately remove all
       remaining Ximian RPMs, and replace them with the corresponding Red Hat
       Linux RPMs.

       You must resolve the version overlap using one of the above choices.
       Failure to do so will result in an unstable GNOME configuration.

     o By default, the Sendmail mail transport agent (MTA) does not accept
       network connections from any host other than the local computer. If
       you want to configure Sendmail as a server for other clients, you must
       edit /etc/mail/sendmail.mc and change the DAEMON_OPTIONS line to also
       listen on network devices (or comment out this option entirely using
       the dnl comment delimiter). You must then regenerate
       /etc/mail/sendmail.cf by running the following command (as root):

       m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf

       Note that you must have the sendmail-cf package installed for this to
       work.

     o CUPS is now the default print spooler, and redhat-config-printer is
       the recommended tool for configuring it. It may be launched from the
       System Settings menu, using the Printing menu entry. LPRng is still
       provided, and upgrades from previous installations using LPRng will
       continue to use it.

     o GNOME Print Manager, a simple graphical print queue management tool,
       is now included. It may be launched from the System Tools menu, using
       the Print Manager menu entry. In addition, when a print job is in the
       queue, an icon will appear in the panel's system notification area.

     o The fileutils, textutils, sh-utils, and stat packages have been
       replaced by the newer coreutils package.

     o The default configuration of PHP has changed since; the short_open_tag
       setting now defaults to Off, as in Red Hat Linux 7.<x> releases.
       Modules are now loaded via .ini files placed in the /etc/php.d
       directory.

     o Support for XHTML1 - the reformulation of HTML in XML - has been
       improved. This has been done by adding the xhtml1-dtd package,
       installing the DTDs in the system catalog, and adding native support
       in the libxml2 and xsltproc tools.

     o The redhat-switchmail command and package have been renamed
       redhat-switch-mail. The redhat-switchmail-gnome package has been
       renamed redhat-switch-mail-gnome.

Packages Removed

   The following packages have been removed from Red Hat Linux 8.0.92:

Kernel Notes

   This section covers issues that are related to the Red Hat Linux 8.0.92
   kernel.

     o Advanced Configuration and Power Interface (ACPI) support has been
       enabled in Red Hat Linux 8.0.92. We are aware that there are many
       computers on which this functionality may not work correctly. In
       particular, some systems may fail to boot.

       If your system does not boot, the ACPI implementation in either the
       kernel or your computer's BIOS may be at fault. Try booting with the
       kernel option acpi=off - if that fixes the problem, please report the
       bug by running the script /usr/sbin/report-acpi-bug. Note that this
       script only works if your machine is successfully connected to the
       Internet, as it sends an email.

       If your machine is not connected to the Internet, or if you wish to
       track the progress of the bug report, please report the problem in
       Bugzilla at http://bugzilla.redhat.com/bugzilla/. Please attach to the
       bug report the output of the following two programs. Note that both
       must be run as root:

       /usr/sbin/dmidecode

       /usr/sbin/acpidmp

       If the acpi=off kernel option does not resolve your problem with the
       system not booting, please report that problem in Bugzilla with as
       much system information as you can gather. In these cases, the problem
       is probably is not related to ACPI.

       If the acpi=off kernel option resolves a problem other than the system
       not booting, please report it via Bugzilla, including the output of
       dmidecode and acpidmp as described above.

     o Fresh installations of Red Hat Linux 8.0.92 will enable the
       experimental HTree feature on new ext3 filesystems.

       The HTree feature makes file creation, deletion, and lookup faster. On
       filesystems that have HTree enabled, these file operations should not
       get significantly slower as the directory grows in size.

       Red Hat requests that users also enable the HTree feature on existing
       filesystems for testing purposes. If you wish to enable the new HTree
       feature on an existing filesystem (for example after an upgrade), you
       must issue the following command for each filesystem:

       tune2fs -O dir_index /dev/<filesystemdevice>

       Afterwards, remount the filesystem (or reboot the system). This will
       enable the HTree feature for any new directories that are subsequently
       created, but will not convert existing directories. To convert
       existing directories, issue the following command:

       e2fsck -fD /dev/<filesystemdevice>

       You can remove the HTree indexing feature from a filesystem by issuing
       the following command:

       tune2fs -O ^dir_index /dev/<filesystemdevice>

       You can then remove the indices from the directories by issuing the
       following command:

       e2fsck -fD /dev/<filesystemdevice>

       If you mount a filesystem that has HTree enabled under an older
       kernel, the HTree flag will be removed automatically from any
       directory that is modified while running under the old kernel. You
       will therefore lose the performance of HTree on such directories, but
       you will always be able to access HTree directories (and your data) on
       any kernel.

       There is one important caveat (though one that will affect very few
       users): if you boot an older kernel and mount an HTree-enabled
       filesystem as an ext2 read-write (not ext3, and not read-only ext2)
       filesystem, you must run fsck -f to fix the filesystem before
       remounting it as an ext3 filesystem on a kernel that supports the
       HTree feature.
