   An update that has 11 recommended fixes can now be
   installed.

Description:

   This update for saptune fixes the following issues:

   - Resetting all values to clean the system during package removal

   - Fix saptune issues with /etc/security/limits.conf. (bsc#1124485)

   - Add deprecated message to the description of some notes set scheduler
     for note SUSE-GUIDE-01 correctly.(bsc#1123808)

   - Ship both versions of saptune in one package to support a smooth
     migration controlled by the customer. See man saptune-migrate(5) for
     more information.

   - Support note name changes and note deletion during update of saptune v2
     from SLE12 to SLE15.

   - Support different SAP Note definitions and solution definitions related
     to the used operation system version (distinguish between SLE12 and
     SLE15 at the moment)

   - Remove calculation of optimized values, only set the values from the
     configuration file irrespective of the current system value. Current
     system value can be increase or decrease. ATTENTION: saptune no longer
     respects higher system values. Use the override option to change the
     values of the Note definition files, if needed. (bsc#1124488)

   - Mark the Notes SUSE-GUIDE-01 and SUSE-GUIDE-02 as deprecated in saptune
     v1 and remove these Note definitions from saptune v2. (bsc#1116799)

   - Add bash-completion for saptune.

   - Add action 'show' to the 'note' operation to print content of the note
     definition file to stdout.

   - Add new action 'create' to support the customer/vendor while creating a
     vendor or customer specific file in /etc/saptune/extra using the
     template file /usr/share/saptune/NoteTemplate.conf

   - Simplify file name syntax for the vendor files available in
     /etc/saptune/extra. Old file names still valid and supported.

   - Add header support (version, date, description) for the vendor files
     available in /etc/saptune/extra as already available for the note
     definition files in /usr/share/saptune/notes

   - No longer write or remove entries from /etc/security/limits.conf.
     Instead add or remove drop-in files in /etc/security/limits.d The
     filename syntax for the drop-in files /etc/security/limits.d is
     saptune-<domain>-<item>-<type>.conf. The limits entry syntax inside the
     Note definition files changed to support more than one limits settings
     in the definition file. (bsc#1128322)

   - Preserve comment sections of the security limits file
     /etc/security/limits.conf. Especially, if this is the only content of
     the file. (bsc#1124485)

   - Work with the current Note definition file to define the pagecache
     settings. (bsc#1126220)

   - Setting of UserTaskMax by applying the related SAP Notes in the
     postinstall of the package. (bsc#1124489)

   - Starting to support severities INFO, WARNING, ERROR and DEBUG for the
     logging and add a defined format for the log messages.

   - Remove saptune as active tuned profile during action 'saptune daemon
     stop' - start/stop services, if requested by SAP Notes, but do not
     enable/disable these services. (bsc#1128325)

   - Adapt the parameter oriented save state file handling (store and revert)
     to the special needs of the security limits parameter. (bsc#1124485)

   - Disable parameter settings using an override file. (bsc#1124486)

   - Store the order of the note as they are applied to get the same system
     tuning result after a system reboot as before.

   - Correct the revert of the vm.dirty parameters by handling their
     counterpart parameters in addition. (bsc#1124487)

   - Adjust operation customize to the new configuration files and override
     location and enable customize option for vendor and customer specific
     files in /etc/saptune/extra. (bsc#1124487)

   - Change output format of the operations list, verify and simulate.
     (bsc#1124487)

   - Display footnotes during 'verify' and 'simulate'. (bsc#1124487)

   - Remove Netweaver formula for page cache calculation. Use the HANA
     approach '2% system memory' for both.

   - Display a warning message, if a [block] section is found in the Note
     definition file because on systems with a huge number of block devices
     this operation may take some time.

   - Add force_latency handling to 'cpu' section. Use the files in
     /sys/devices/system/cpu/cpu* instead of /dev/cpu_dma_latency. Remove the
     parameter from the tuned.conf file and add it to the SAP note files
     '1984787' and '2205917'

   - Add action 'saptune revert all' and add parameter based saved state
     files to support proper revert functionality. (bsc#1124487)

   - Add override file handling for the solution definition using
     /etc/saptune/override/solution. (bsc#1124486)

   - Read solution definition from file /usr/share/saptune/solution instead
     of static coding inside of saptune. (bsc#1124486)

   - Make sure a note, which is part of an applied solution definition, but
     was reverted manually later, will NOT applied again after a system
     reboot.

   - One configuration file per SAP Note. (bsc#1124486)

   - Add new SAP Notes and adapt content of SAP Notes.

   - Handle different locations of the new configuration files
     (/usr/share/saptune/note, /etc/saptune/extra). (bsc#1124486)

   - Allow parameter override by the customer. (bsc#1124486)

   - Expand section handling of the 'ini file' handler to handle the new
     configuration file entries. Supported sections: version, reminder,
     login, mem, vm, block, limits, sysctl, pagecache, cpu, service, rpm,
     grub. (bsc#1124486)

   - Remove new line from println arg list of main.go to support newer go
     versions. (bsc#1120741)
