 # TODO:
 # - if running at systemd, cron job is not neccessary (it has the timers)
-# - make upgrade cleaner than it is now. after upgrade sysstat does not work until data file is changed for next day:
-# I sysstat-11.0.8-3.x86_64
-# R sysstat-10.1.6-5.x86_64
-# # sar -q
-# Invalid system activity file: /var/log/sa/sa13
-# File created by sar/sadc from sysstat version 10.1.6
-# Current sysstat version can no longer read the format of this file (0x2171)
-#
-# # service sysstat restart
-# System Activity Data Collector service is not running.
-# Starting System Activity Data Collector service....................[ FAIL ]
-# sensors_init: Kernel interface error
-# Invalid system activity file: /var/log/sa/sa13
-# File created by sar/sadc from sysstat version 10.1.6
-# Current sysstat version can no longer read the format of this file (0x2171)
-#
-# So add automatic conversion using sadf (see howto on project page)
-# after update to version >= 11.1
 #
 # Fix or remove  install.patch (seems systemd files are installed now)
