  rename 'system state' line to 'systemd system state' to prevent misunderstandings.
  add virtualisation information.
• add tuning state to 'saptune status' output.
  The check of the tuning state (an internal 'verify' operation) can be skipped by using the flag '--non-compliance-check'.
  In this case the tuning state will be reported as unknown (checking disabled)
  'saptune status' will exit with a return code of '4', if the saptune service is enabled, the system is tuned, but the tuning state is 'not compliant'.

• introduce an additional parameter 'SKIP_SYSCTL_FILES' in the /etc/sysconfig/saptune configuration file, which contains a comma separated list of sysctl.conf files or directories containing sysctl.conf files, which should be excluded from the 'additional defined' WARNING messages.
  Default is
  SKIP_SYSCTL_FILES="/boot"
  to skip the WARNINGS for '/boot/sysctl.conf-'
• check in preinstall and posttrans of the package installation, if the active tuned profile is still 'saptune', even that this profile no longer exists. If yes, try to remove it.

  Add some additional log messages to identify the cause and add a hint to the man page.
• fix block device settings (e.g. NRREQ) for multipath devices
  (bsc#1193576)
• 'saptune verify' will now report a non existing sysctl or sys parameter as 'not available on the system' (footnote) and this parameter will not affect the compliance state.
  But a warning is displayed to raise attention to may be typos in the parameter name.
• 'saptune status' now reports the 'real' unit state, no mapping of not running (inactive) service to simply 'stopped' any more.
  (bsc#1194334)

  Add an own systemd service file for saptune to start/stop tuning of parameter values during a reboot of the system.
  Add a new saptune action 'service' to handle the saptune.service supporting start/stop/enable/disable/status a.s.m.
  The saptune action 'daemon', which handled tuned.service in the past, is now flagged as 'deprecated' and internally linked to the new action 'service'
  (jsc#SLE-5589, jsc#SLE-5588, jsc#SLE-6457)

• add a sanity check to detect Note definition files which do not exist anymore, because they were renamed or deleted, but without reverting them before.
  saptune will now print an error message, remove the Note from the tracking variables in /etc/sysconfig/saptune and try to revert the related parameter settings.

  Use an override file to define the values fitting your system requirements
  (bsc#1170672)

• support empty parameter values in the Note definition files and not only in the override file.
  This is needed for the support of SAP Notes like 2382421, so that the customer is able to simply use an override file to define some special parameters instead of using a customer specific Note definition file.
  needed for bsc#1170672
  (jsc#TEAM-1702)

• report an 'error' instead of 'info' and set the exit code to '1', if we reject the apply of a solution
  (bsc#1167213)

• Skip perf bias change if secure boot is enabled
  When a system is in lockdown mode, i.e., Secure Boot is enabled, MSR cannot be altered in user-space. So check, if Secure Boot is enabled using the mokutil utility and skip setting the perf bias in case it is.
  (bsc#1176243)

• rework the internal block device handling to speed up the apply of block device related tunings on systems with a high number of block devices.
  (bsc#1178207)

• change block device handling to handle multipath devices correctly. Only the DM multipath devices will be used for the settings, but not its paths.

• support note definition versions containing digits, upper-case and lower-case letters, dots, underscores, minus and plus signs.
  (bsc#1182289)

• fixed issue with 'verify' operation and parameter 'VSZ_TMPFS_PERCENT'. As this parameter is only used to calculate the value of 'ShmFileSystemSizeMB' (if it is not set to a value >0 in the Note definition file) it will not be checked and compared during the saptune operation 'verify'. A footnote is pointing this out.
  (bsc#1182009)

  (jsc#TEAM-1679)

• Add enable/disable for systemd units and support all systemd unit types in section [service]
  (jsc#TEAM-1701)

• remove script /usr/share/doc/packages/saptune/sapconf2saptune and the associated man page
  (jsc#TEAM-1707)

• implement staging of Note definition file and solution definitions.
  The idea is to freeze the saptune configuration to avoid config changes on package update when adding/removing/changing notes or solutions within the package
  (jsc#TEAM-1844)

• support custom solutions and override files for solutions.
  Partners and customers will now be able to define their own solution definitions by using files in /etc/saptune/extra or to override the shipped solution definitions by using override files in /etc/saptune/override
  (jsc#TEAM-1706)

• support for device specific configurations
  only supported for the [block] section, tags are 'vendor' and 'model' to support special block devices of a dedicated hardware vendor or a dedicated hardware model

  (jsc#TEAM-825)

• add support for [sys] section and handle double configurations for parameters defined in the [sys] section
  (jsc#TEAM-3342)

• check system sysctl config files as mentioned in the comments of /etc/sysctl.conf and in man page sysctl.conf(5) for sysctl parameters currently set by saptune notes. Print a warning and a footnote for 'verify' and 'customize'.
  (jsc#TEAM-1696)

• add support for [filesystem] section
  only check filesystem mount options, not modify. Starting with filesystem type 'xfs'
  (jsc#TEAM-4093)

  (jsc#TEAM-4260)

2.0.3

• changes to the UserTasksMax handling in saptune

  In SLE15 the limit is removed from the systemd login manager and therefore the setting is no longer supported in SLE15 by saptune.

  On a system running SLE12 we do not restart the logind service, but try to reload the new configuration after creating or removing the drop-in file for UserTasksMax by using
  'systemctl reload-or-try-restart systemd-logind'
  as display managers do not like a restart of the logind service.
  (bsc#1161791)

2.0.2

• support multi-queue I/O scheduler for block devices
  (bsc#1152598)

• if a parameter is not supported by the system, the note action 'verify' will no longer report this as an error even if the value is not compliant.
  Additionally if there is a non compliant 'grub' parameter, which has a compliant 'alternative' setting availabel (see man page saptune-note(5) for details), the note action 'verify' will no longer report this as an error
  (bsc#1159671)

• add action 'delete' to the 'note' operation to delete a customer or vendor specific Note definition file including the corresponding override file if available.
  A confirmation is needed to finish the action.

  add action 'rename' to the 'note' operation to rename a customer or vendor specific Note definition file to a new name. If a corresponding override file is available, this file will be renamed too.
  A confirmation is needed to finish the action.

  If the Note is already applied, the action will be terminated with the information, that the Note first needs to be reverted before it can be deleted or renamed.
  (jsc#SLE-9283)

• check, if sapconf service is available before disabling this service during 'saptune daemon start'
  (bsc#1156049)

• Inform the customer that - by intention - the command
  'saptune note customise '
  does not apply changes immediately. It just changes the configuration in the 'override' file. These changes have to be applied in a second step.
  This is explained in the man page saptune_v2(8) and a message is printed in the logs and on the screen to inform the customer.
  (bsc#1142467)

• Add warning to man page, not to rename/remove/modify active configurations
  (bsc#1149002)

• check, if the directory /etc/security/limits.d exists before writing the limits drop-in file. If not, create it.

• add the '--no-pager' option to 'systemctl --list-unit-files' to get all services at once.

• add missing search pattern to the update helper script to find all old and superfluous notes during upgrade from SLE12 to SLE15

  For the daemon operations do not exit with an error, if a note definition file does not exist. Instead only log and print an error message, but continue with applying the other notes
  (bsc#1142526)
