Also there is a difference between the use of /etc/sysctl.conf at boot and when using either the proposed -p option or the shell command: At boot we start out with the default values. When re-reading /etc/sysctl.conf the current state is the base. That is very relevant if you e.g. remove a line from /etc/sysctl.conf (to go back to the default). Mike
