How does one ship the product to third parties and allow administrators to make changes? Essentially, what happens with Security-Enhanced Linux is in order to address security issues that exist out there, you have to have a mechanism that controls all access on a system. When you think of normal Linux access control, you are dealing only with processor access, file systems, control interfaces and networking, and they are very far removed from the normal Linux access mechanism. For example, even if you control access to writing files that MySQL uses, MySQL is still attacked over the network or via interprocessor communication. People aren't used to dealing with all of the kinds of access that a complex program like MySQL needs, and more importantly, the interaction between [the accesses] gets complicated..."
