There are observed issues upgrading Red Hat Linux 6.x, 7.0, 7.1, 7.2, and
7.3 systems running Ximian GNOME. The issue is caused by version
overlap between the official Red Hat Linux RPMs and the Ximian RPMs. Please be
aware that this is a configuration unsupported 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 methods. Failure to do so will result in an unstable GNOME
configuration.
KDE has been updated to 3.0.0 and includes usability enhancements
as well as some new applications and features.
Anti-aliased fonts may appear to be non-functioning after the
upgrade to KDE 3.0.0. This issue is related to a feature addition: Due
to the Qt 3.0 update, it is now possible to use anti-aliased and
non-antialiased fonts at the same time in Qt applications. Since the
default fonts for the KDE desktop environment are bitmap fonts and
therefore can not be anti-aliased, just turning on the enable
anti-aliased fonts button in KDE will not modify the look of all
applications. To get anti-aliased fonts in menus, window titles, etc.,
change the fonts for these elements (for example, by replacing
Helvetica with Helmet and Courier with Lucidatypewriter).
Red Hat Linux now includes a port of the Debian
alternatives system, as a way to support multiple packages
providing a particular service. Every binary/file that
would be in common between the multiple packages is replaced
with a symlink to /etc; this then resolves to the version
of that file for the alternative in question. For example:
/usr/sbin/sendmail -> /etc/alternatives/mta ->
/usr/sbin/sendmail.sendmail
These symlinks are added and managed by
/usr/sbin/alternatives. See man 8
alternatives for more details
Currently, Red Hat Linux offers Sendmail and Postfix as two Mail Transport
Agent (MTA) alternatives. For print daemon alternatives, the choices
are LPRng and CUPS.
Note that the configurations for LPRng and CUPS are completely separate. If
you switch from one printing system to another, you will have to
reconfigure your printers. Similarly, postfix and sendmail
have separate configuration files.
XFree86 has been updated to version 4.2.0. Included in this
version is new support for the following graphics chipsets:
ATI Radeon 7500 (2D/3D), Radeon 8500 (2D)
ATI Radeon Mobility M6/M7 (2D/3D)
Intel i830 (2D/3D)
Matrox G550
nVidia nForce
3DLabs Permedia 4
Older S3 (non-Savage, non-ViRGE) chipsets
NOTE: The nVidia GeForce 4 chipset is
not supported by the "nv" driver in XFree86
4.2.0. The XFree86 "vesa" driver, which uses a video card's VESA BIOS
to initialize video modes, may work as a temporary workaround until
official support is available in a future release.
Mozilla has been updated to 0.9.9. This release includes MathML
support, javascript profiling, S/MIME support in mail and news, tabbed
browsing, LDAP support in the address book, and a large number of bug
fixes.
The Evolution mailer/calendar/contact manager has been added.
Evolution includes POP, IMAP, and local mail support, iCalendar
support for calendaring and scheduling, and integrated contact
management and online tasklists.
MrProject, a project management tool, has been added. MrProject
supports planning and tracking projects, including Gantt charts,
dependencies, and resource allocations.
The GnomeMeeting video conferencing application has been added.
GnomeMeeting is an H.323 compliant videoconferencing tool, which
supports H.245 tunneling and also an audio-only mode.
Red Hat Linux now supports both Traditional and Simplified Chinese in
addition to support for American English, French, German, Italian,
Japanese, Korean, and Spanish.
Support for DVD-R, DVD+RW, and DVD-RW drives has been included and
is available in the dvdrtools package.
Formatting DocBook XML documents using the XSL stylesheet language
is now possible. For more information, refer to the
xmlto(1) manual page.
The DocBook document type definitions (DTDs) have been merged into
one RPM package called
docbook-dtds.
The gPhoto2 package has been added to
the distribution. gPhoto2 is a software
application and interface library for digital cameras. The
gPhoto2 package also includes
gtKam, a graphical digital camera interface
that uses gPhoto2.
Kamera, a Konqueror plugin for digital
cameras, has been added, as well. The older
gphoto application (0.4.3) is deprecated
and may be removed in a future release.
The initscripts now disable DMA on IDE CD-ROMs by default. To
enable it, make a
/etc/sysconfig/harddisk<device>
file that contains USE_DMA=1, where
<device> is the device of your disk
or CD-ROM (such as hdc).
/sbin/service now changes to the root directory
before starting or stopping services. There are also changes in the
way /sbin/service handles environment
variables. For example, if an init script relies on special
environment variables (PATH, etc.), the script needs to explicitly set
these variables rather than expecting to inherit them.
The bcm5820 package has been replaced
with the hwcrypto package. The
hwcrypto package also includes support
for the AEP 1000 cryptographic accelerator.
The xscanimage program has been deprecated and
may be removed in a future release of Red Hat Linux. The xsane
program should be used instead.
The rp3 package has been removed; to
configure dial-up access use the
redhat-config-network
package.
The ircii package has been replaced with the
epic package. epic is mostly
compatible with ircii scripts and includes more
features than ircii.
The mkkickstart package has been
removed. The ksconfig program should be
used instead; you can also edit the
/root/anaconda-ks.cfg generated by the
installer.
The patchutils package of utilities for
manipulating patch files is now included. Patch files are often used
in software development.
The autoconf253 and
automake15 packages are included, which updates
autoconf to version 2.53 and automake to version 1.5 for those who need
updated development environments.
The glibc-kernheaders package has been added
and will replace the kernel-headers package.
The postgresql package has been
updated. To preserve your data, dump the data using the
pg_dumpall command before upgrading, then restore
the data after the upgrade is complete. Refer to the pg_dumpall(1) man page for more information.
The Red Hat Network Panel Applet is included on GNOME desktop panels by
default. This applet allows you to receive Red Hat Network notices and download
updates for your Red Hat Linux system. Note that the Red Hat Network Panel Applet does
not appear on your GNOME desktop panel if you have upgraded from a
previous version of Red Hat Linux. To add this to your panel, choose the
following:
Main Menu => Applets =>
Monitors => Red Hat Network Alert Notification
