...files.

One might suppose that a ``most common subset'' of system files could be designated and loaded, and this is true. However, specifying such a subset is ever harder as programs depend on more and more files for configuration and auxiliary information. This approach also increases the user's responsibility for system administration, which we regard as a poor way to design systems.
