Yup.  Or use a database and a template-driven compiler.  See "Configuration management and security", IEEE Journal on Selected Areas in Communications, 27(3):268-274, April 2009, by myself and Randy Bush, http://www.cs.columbia.edu/~smb/papers/config-jsac.pdf (the system described is Randy's work, from many years ago).
