[. . . ] Release Notes for SUSE Linux Enterprise Server 10 Service Pack 2 Release Notes for SUSE Linux Enterprise Server 10 Service Pack 2 Version 10. 2. 1, 13. May 2008 Abstract These release notes are generic for all SUSE Linux Enterprise Server 10 based products. Some parts may not apply to a particular architecture/product. Where this is not obvious, the respective architectures are listed explicitly. [. . . ] Update from SUSE Linux Enterprise Server 10 SP1 · New on disk format of new Sysstat package The new features of the new Sysstat package needs a new on disk format of the data files. After the update of the sysstat package the old collected data can no longer be used. · Changed order of starting network interface 12 Update-Related Notes The order in which network interfaces will be started has changed. The new order is now bond interfaces first, then vlan, dialup tunnel and finally bridge interfaces. 6. 3. Update from SUSE LINUX Enterprise Server 9 · Becoming Superuser Using su By default, calling su to become root does not set the PATH for root. Either call su - to start a login shell with the complete environment for root or set ALWAYS_SET_PATH to yes in /etc/default/su if you want to change the default behavior of su. · Forwarding xauth keys between users with sux The shell script sux was removed. The functionality of forwarding xauth keys between users is now handled by the pam_xauth module and su. · NTP-Related Files Renamed For reasons of compatibility with LSB (Linux Standard Base), most configuration files and the init script were renamed from xntp to ntp. · Changed tar behavior in SUSE Linux Enterprise Server 10 Under SUSE Linux Enterprise Server 9, when extracting a directory from a tar archive that already existed as a symbolic link in the target directory, tar would overwrite the symlink with an actual directory. Under SUSE Linux Enterprise Server 10, tar leaves the symlink and places the contents of the archive within it. To enforce the old behavior please use the option --no-overwrite-dir when extracting an archive. · ulimits SUSE Linux Enterprise Server 9 set up the user environment with an unlimited stack size resource limit to work around restrictions in stack handling of multithreaded applications. With SUSE Linux Enterprise Server 10, this is no longer necessary and has been removed. The login environment now defaults to the kernel default stack size limit. To restore the old behavior, add ulimit -Ss unlimited to /etc/profile. local. If you want an automatic configuration of your resource limits suited to protect desktop systems, you may want to install the ulimit package. · Mounting Encrypted Partitions With SUSE Linux Enterprise Server 10, we switched to "cryptoloop" as the default encryption module. SUSE Linux Enterprise Server 9 used twofish256 using loop_fish2 with 256 bits. Now we are using twofish256 using cryptoloop with 256 bits. The old twofish256 is available as twofishSL92. · Reconfiguring Intel and Nvidia Sound Drivers When updating a system with the snd-intel8x0 module (for Intel, SIS, AMD, and Nvidia on-board chips), the system might be unable to load the module at reboot, because the module option joystick was removed from the newer version. [. . . ] Read the documentation in /usr/share/doc/packages/jpackage-utils/ for information. · Loading unsupported kernel drivers To load unsupported kernel drivers automatically during boot, set the sysconfig variable LOAD_UNSUPPORTED_MODULES_AUTOMATICALLY in /etc/sysconfig/hardware/ config to "yes". · Nonexecutable Stack Already introduced for SUSE Linux Enterprise Server 9 on the x86-64 (AMD64) architecture with 64-bit kernels, the Linux kernel in SUSE Linux Enterprise Server also supports nonexecutable stack (NX) on x86 for CPUs that support it (Intel Prescott and AMD64) with 32-bit kernels. For this to work, the kernel with PAE support, kernel-bigsmp, must be installed. [. . . ]
