As I mentioned this is to test a filter driver, so I need to make the OS calls with system as they are checked differently than calls made within Perl; and really that is what I need to test. Things like the chmod example you mention are part of the test, to make sure the filter captures and does not barf on things like a chmod call on a directory. So, yes, it is testing and checking that certain operations work as hoped for.
I should do better with the OS dependency and group better, honestly though this script is much cleaner than the one I inherited, and its about 33% smaller than the original one as well. More cleanup on the OS stuff is on my list, I still have no idea why the System calls are suddenly acting up, but at least I can get by with them for now.
Thanks!
