Most of the functionality don' work in this mode, it just applies the settings, no rollback possible. Disable daemon by setting 'daemon = 0' in /etc/tuned/tuned-main.conf This settings can be overridden if running tuned with '-d' command line option. In such case daemon mode will be used. Resolves: rhbz#1068663 Also fixed interpretation of booleans in main config. Signed-off-by: Jaroslav Škarvada <jskarvad@redhat.com>
