No.
Subscribe creates a notification for the subscribing resource if the
subscribed resource needs a change, e.g. an exec is run. However, file
resources are *always* evaluated, whether notified or not.
The only way to do what the OP wants is to use 'exec { "cp ...":
refreshonly => true }' instead of file { }. Exec is one of the few types
that can be controlled with subscriptions/notifications.
However, that would be poor design.
I'd suggest writing a simple wrapper script to do all that needs doing
and have exec {} call that script instead.
Failing that, put all your commands in variables and exec { "$cmd1 &&
$cmd2 && $cmd3 ...": ... }.
But that's no quite best practice, either.
