Ich kann mich dem Tester nur anschließen: Wenn Redhat den Kernel 2.6 reinbringt, dann ergibt ein Update Sinn, ansonsten kann man at home mit den aktualisierten Vorversionen (hier zufrieden sein.
Und über die Geschichte mit der Paketinstallation seit RH8 breite ich lieber den Mantel des Schweigens ;-)
Was ich vermisse sind Hinweise auf neue (Kernel-)Features. Gibt es wirklich keine?
Wie schaut's mit einem aktuellen Acpi aus? Das war früher imho nicht integriert.
Wie schaut's mit Unterstützung für Speedstep und Power-Now aus? Hat die Technik endlich den Weg in Redhat gefunden, oder muss man immer noch andere Distributionen benutzen oder selbst am Kernel rumpatchen?
Wie schaut's mit Alsa aus? Wird das jetzt standardmäßig verwendet, oder setzt Redhat auf das antike OSS?
This section covers issues that are related to the Red Hat Linux 9.0.93 kernel.
The Red Hat Linux 9.0.93 kernel includes support for ACPI (Advanced Configuration and Power Interface). When booting the Red Hat Linux installation program from CD (and booting the installed system) this kernel uses ACPI on some systems (depending on certain factors such as whether the hardware supports ACPI and the date of its BIOS ACPI implementation). ACPI is used for device enumeration (but not for sleeping). You can disable ACPI by using the following boot option:
acpi=off
NOTE: The ACPI subsystem results in a kernel too big to fit on a diskette; therefore, the kernel placed on boot diskettes does not include ACPI support. In addition, because of these size issues, emergency boot diskettes will not work. You must use rescue mode from the installer instead of an emergency boot diskette.
The Red Hat Linux 9.0.93 kernel includes new Exec-shield functionality Exec-shield is a security-enhancing modification to the Linux kernel that makes large parts of programs including their stack not executable. This can reduce the potential damage of some security holes. Exec-shield is related to the older "non-exec stack patch" but has the potential to provide much greater protection.
Exec-shield's behavior can be controlled via the proc file system. The command used is:
echo > /proc/sys/kernel/exec-shield
Where is one of the following:
- 0 Exec-shield is always disabled
- 1 Exec-shield is disabled, except for binaries that enable it
- 2 Exec-shield is enabled, except for binaries that disable it
- 3 Exec-shield is disabled
NOTE: Binary marking (the ability to identify those binaries that should run with Exec-shield enabled/disabled) is not yet implemented.
The Red Hat Linux 9.0.93 kernel now makes it possible to prevent the loading of kernel modules. This can be useful for system administrators wanting to ensure that only a strictly-controlled set of modules are loaded. To disable kernel module loading, issue the following command:
echo off > /proc/modules
Once this command has been issued, all further attempts to load kernel modules will fail.
NOTE: Once kernel module loading has been disabled, a reboot is required to re-enable it.
The Red Hat Linux 9.0.93 kernel now includes support for laptop mode. When placed in laptop mode, the kernel batches disk I/O, allowing the disk drive to become idle long enough for the drive's power-saving features to take affect. This can result in significant increases in battery runtime.
To enable laptop mode, issue the following command:
echo 1 > /proc/sys/vm/laptop_mode
To disable laptop mode, issue the following command:
echo 0 > /proc/sys/vm/laptop_mode
NOTE: The APM scripts included with Red Hat Linux 9.0.93 automatically enable laptop mode when switching to battery power.
1)Tut mir leid, aber die einzige sinnvolle Info aus dem Test ist, dass redhat auf dem notebook läuft. Den Rest könnte man auch den release-notes entnehmen.
2)Bei der hardware sollte die Geschwindigkeit kein Problem mehr sein.
3)Wer diskussionen mit dem rehat-Mann Havoc P. gelesen hat, kann sich vorstellen wie ein offener Entwicklungsprozeß bei redhat aussieht.

Zum Glück gibts Webmin...
