>Description:
I submit for your consideration a periodic script which I've been
running for a month or so. It checks on the status of all the daemons
started up by the rc system by using rcorder to get the list of all
enabled startup scripts exactly as the system initialisation does (as
in: I copied that chunk of code pretty much verbatim.)
I find this a useful double check after eg. a portupgrade session
where it's all too easy to forget to restart a particular daemon that
has been turned off for updating.
