User manual NOVELL SP2 RELEASE NOTES

[. . . ] 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. Where this is not obvious, the respective architectures are listed explicitly. The instructions for installing this Service Pack can be found in the README file on CD1. [. . . ] This reduces the number of learning events logged to disk, which improves the performance of the system. · LD_ASSUME_KERNEL Environment Variable Do not set the LD_ASSUME_KERNEL environment variable any longer. In the past, it was possible to use it to enforce LinuxThreads support, which was dropped. If you set LD_ASSUME_KERNEL to a kernel version lower than 2. 6. 5, everything breaks because ld. so looks for libraries in a version that does not exist anymore. 6. 2. 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. [. . . ] Use the same variable names but without the RC_ namespace prefixes, for example, use LANG instead of RC_LANG. For information about locales in general, see "Language and Country-Specific Settings" in the Reference Manual. · Configuration of kdump The kernel is crashing or otherwise misbehaving and a kernel core dump needs to be captured for analysis. A description on how to setup kdump can be found under the following URL: http://www. novell. com/ support/search. do?cmd=displayKC&docType=kc&externalId=3374462&sliceId=SAL_Public · Realtime Applications When running real-time applications on larger systems, lower maximum latencies can be achieved by employing the new disable_buffer_lru kernel command-line option.
