source => \"puppet://server/module/myscript\",
mode => 755,
require => File[\"/usr/local/scripts\"]
}
Multiple dependencies can be specified by providing a comma-seperated list
of resources, enclosed in square brackets:
require => [ File[\"/usr/local\"], File[\"/usr/local/scripts\"] ]
Note that Puppet will autorequire everything that it can, and
there are hooks in place so that it's easy for resources to add new
ways to autorequire objects, so if you think Puppet could be
smarter here, let us know.
In fact, the above code was redundant -- Puppet will autorequire
any parent directories that are being managed; it will
automatically realize that the parent directory should be created
before the script is pulled down.
Currently, exec resources will autorequire their CWD (if it is
specified) plus any fully qualified paths that appear in the
command. For instance, if you had an `exec` command that ran
the `myscript` mentioned above, the above code that pulls the
file down would be automatically listed as a requirement to the
`exec` code, so that you would always be running againts the
most recent version.

'main' stage. You can create new stages as resources:
stage { [pre, post]: }
To order stages, use standard relationships:
stage { pre: before => Stage[main] }
Or use the new relationship syntax:
Stage[pre] -> Stage[main] -> Stage[post]
Then use the new class parameters to specify a stage:
class { foo: stage => pre }
Stages can only be set on classes, not individual resources. This will
fail:
