TokyoCrusaders92 asks: "Like a lot of other organizations (800 staff, 5000 students) we have a mix of Windows, Novell & Linux (primarily Linux) for our IT infrastructure. We now have a multitude of config files, firewall rule bases, shell scripts, and so forth which are managed by multiple people and groups. Recently, we started using RCS for version control of the firewall rule-base, but this doesn't seem like it would scale up to larger groups of users. While thinking about this, it would seem that the critical features would include: version control; logging; multiple users; secure authentication; and integrity checking. What are other people using to manage their config files?"
