This will cause the whole filesystem to be 'relabeled' which might take a while, depending on the size of the filesystem and the speed of the machine, so be aware of this possibility. This will signal SELinux on the next reboot that the filesystem has changed (the changed password) and allow the change to be loaded. At the prompt ,enter: touch /.autorelabel.
