Suse now support each previous service pack for six month since the next service pack was release. So For SLES 11, support of SP1 lasted for six month after SP2 was released (February 2012) and now it over. Actually SP2 was the first service pack released after Suse development was moved back to Germany and it was quite problematic at the beginning.
In any case after six month you need to upgrade to preserve support.
Sudo configuration changed
Installer changed but still berable.
Many development packages and sub-packages as possible have been moved to the SDK.
The System Security Services Daemon (sssd) was added to SLE 11 SP2 to provide an alternative method to retrieve user and group information from LDAP directories and to perform authentication through LDAP or Kerberos. It is provided as an alternative to the nss_ldap and pam_ldap (or pam_krb5) Modules. Compared to those modules sssd offers some advantages:
With SLE 11 SP2 the YaST2 ldap-client module can be used to setup sssd for LDAP (and/or Kerberos) Authentication. The YaST to ldap-client module can also be used to switch from a nss_ldap/pam_ldap based setup to sssd and back.
Some additional notes:
SUSE Linux Enterprise Desktop 11 comes with an improved update stack and the command line tool zypper to manage the install/update packages and repositories.
The default file system in new installations was changed from ReiserFS to ext3 with SUSE Linux Enterprise Desktop 11. A public statement can be found at http://www.suse.com/products/server/technical-information/#FileSystem.
This release of SUSE Linux Enterprise Desktop ships with AppArmor. The AppArmor
intrusion prevention framework builds a firewall around your applications by limiting
the access to files, directories, and POSIX capabilities to the minimum required
for normal operation. AppArmor protection can be enabled via the AppArmor control
panel, located in YaST under Security and Users. For detailed information about
using AppArmor, see the documentation in
The AppArmor profiles included with SUSE Linux have been developed with our best efforts to reproduce how most users use their software. The profiles provided work unmodified for many users, but some users find our profiles too restrictive for their environments.
If you discover that some of your applications do not function as you expected, you may need to use the AppArmor Update Profile Wizard in YaST (or use the aa-logprof(8) command line utility) to update your AppArmor profiles. Place all your profiles into learning mode with the following: aa-complain /etc/apparmor.d/*
When a program generates a high number of complaints, the system's performance is degraded. To mitigate this, we recommend periodically running the Update Profile Wizard (or aa-logprof(8)) to update your profiles, even if you choose to leave them in learning mode. This reduces the number of learning events logged to disk, which improves the performance of the system.
SuSEfirewall2 is enabled by default. That means that by default you cannot log in from remote systems. It also interferes with network browsing and multicast applications, such as SLP and Samba ("Network Neighborhood"). You can fine-tune the firewall settings using YaST.
This new version of the e1000e driver adds support for the following devices: 82567LM Gigabit Network Connection 82574L Gigabit Network Connection 82567V-3 Gigabit Network Connection 82579LM Gigabit Network Connection 82579V Gigabit Network Connection 82583V Gigabit Network Connection 82567V-4 Gigabit Network Connection 82566DC-2 Gigabit Network Connection
It is possible to run SUSE Linux Enterprise Desktop 11 on a read-only root filesystem. Due to the huge number of possible configurations, this is currently not a supported scenario.
The /tmp and
/var directories need to be on a separate
partition and cannot be mounted read-only.
After the installation has finished and all services are configured, login as root and do the following modifications:
/etc/fstab and add "ro" to the mount options of the root
rm /etc/mtab ln -s /proc/mounts /etc/mtab mkdir /var/lib/hwclock mv /etc/adjtime /var/lib/hwclock ln -s /var/lib/hwclock/adjtime /etc/adjtime # the following two steps are only necessary if you use dhcp: mv /etc/resolv.conf /var/lib/misc/ ln -s /var/lib/misc/resolv.conf /etc/resolv.conf # Now mount root filesystem read-only and reboot mount -o remount,ro / reboot
