MIT Athena deals with this problem both for SysV-like systems
(Solaris, Irix, maybe Linux) and NetBSD with monolithic rc.conf by
writing a small program called syncconf that reads the Athena-specific
configuration file (/etc/athena/rc.conf, as it happens) and
propagating the information in that to appropriate system
locations. It seems to be a pretty good approach for making
cookie-cutter systems, and it's survived being used on five or so
different operating systems.
