(In reply to Franck Bui from comment #2) > Please attach the output of `systemd-analyze cat-config sysctl.d` Sorry for the late reply. i execute the file and is read, but for example if i apply net.ipv6.conf.all.disable_ipv6=1 using yast2 it will apply immediately, but if i reboot the system the ipv6 will still appear, and the command will show that systemd read the file, but ipv6 still is enabled.
