Yes, but as I neglected to mention initially, at least one of the scripts in question will be a widely distributed script under the control of sysadmins with their own concerns. It has to be system only perl or a reinvented wheel.
I will probably check the YAML and Config:: modules to see if any are already used by the projects my other script is geared toward, but I do need the most secure system only method I can get hold of.
