That was what I was missing; instantiation. Thanks. :)

It does, but I think something is off inside puppet's guts.

As far as I can see in the source (ruby code at
https://github.com/puppetlabs/puppet/blob/master/lib/puppet/provider/service/upstart.rb#L47)
it does "initctl list", and picks the first word of each line, unless
the service in question is "network-interface" or
"network-interface-security".

It looks like puppet does not handle instances in a generic way, but
special cases it for "network-interface" and
"network-interface-security", and then hardcoded with INTERFACE=foo and
JOB=bar.

It looks like the instance variable name differs between services, so if
my assumption is correct, I wonder what would be the "generic" way of
enumerating services the correct way would be to find this variable for
all instanciated services.
