>Description:

The service(1) helper script should gain two features:

	- a option to list all services that currently have a daemon
	  process running (simmilar to "service -e" but checking for
	  pidfile in the rc.d script, plus file existance and valid
	  pid in it) -- maybe: service -d

	- a command to restart all services output by above option,
	  i.e. run something like "$script restart" for everything
	  output by "service -d" -- maybe: service restart_all

That way after a binary update of userland the user (or sysinst) could simply
do "service restart_all" in case they can't reboot immediately.

Updating e.g. ssh/sshd sometimes can make the running sshd(8) stop working,
as the child/parent protocol changed.
