Puppet users - Mar 2011 - "schedule is a metaparam; this value will inherit to all contained resources" ?

Hi,

I have a type named apt::package, that installs packages on Debian base
systems. By default, it sets the schedule to something I defined, to
prevent package updates from happening outside maintenance hours.

Now, in a specific class, I do this:

# This is normally a manual puppet run, so ignore the maintenance window
Apt::Package {
    schedule => "common::schedule::always",
}

This results in the following text being written to the log:

"puppet-master[30601]: schedule is a metaparam; this value will inherit to
all contained resources"

This message doesn''t give many results in Google, so I wonder:

What exactly does that mean?
Does it do something unexpected (I expect the default to apply to any
apt::package defined in that specific class, and nothing else)?
Why is it necessary to log this, if nothing is wrong?

Best regards,
Martijn.

It means that if you have any other resources *inside* the
Apt::Package definition, they will also inherit the schedule parameter
you''re passing in.

It''s warning you that it will automatically inherit the schedule
metaparameter because this may not be what you expected to happen.
