GAH! See, I just slipped up and showed my age. I'm thinking of the Stratus VOS filesystem, which did change the modifier when you edited a file. You're right; UNIX/Linux files have an owner, which doesn't change on modification. Which shoots a big blazing hole in my argument. You can back into who modified what if files were changed in a big batch, and they also created a few new files - but you could also back into that via login times. Since those days, it's less that I've seen the individual-user system work at scale - it's that I've seen the single role account fail, repeatedly. I've managed to avoid permissions hell with a few well-chosen supplemental groups, but maybe I'm too optimistic that what used to work in one environment will work in another. Ask me in six months. :)
