In addition to what Paul says, the way that something like this would normally be handled in Puppet is: 1) If process A is not running, start process A (this could be done via an Exec) 2) Step 1 may fail, because the binary used to launch process A is not installed. So, you'd also have a Package resource that would manage the package that contains that binary. At this point, the Exec can be told to depend on the Package such that trying to start process A will automatically trigger the installation of the necessary Package if it's not already installed. 3) The Package (or particular configuration thereof) may require a mount point to be available. So, you'd also have a Mount resource that would configure that mount point. At this point, the Package resource configured in step 2 can be told to depend on the Mount resource such that installing the Package will automatically set up and mount the Mount point resource. 4) Your node's manifest would only contain the Exec set up in step 1; everything else will automatically be configured through the defined dependency relationships.
