argus and upstart (linux)

[Barry Kolts]

Peter,

I wrote the two attached upstart jobs a couple of years ago. They are 
running on Ubuntu server 12.04 and seem to work just fine. I learned 
just enough about Upstart to write these, so I'm no Upstart expert. Use 
them as a guide or just use them.

I just read this week that Canonical has decided to drop Upstart and 
follow Debian's lead and go with systemd. So we will have to learn how 
to use systemd.  Canonical said they won't change in the up coming 
release 14.04 but will change to systemd in 14.10.

Hope this helps,
Barry
