In particular, taking a leisurely stroll through /etc is quite a treat if you enjoy a well planted and diverse bed of configuration cultures. Over on one end you have papersize, a file containing a single word with seemingly no relation to any installed software. In httpd.conf we have a sort of SGML that’s mostly line oriented CDATA. aliases and many other mail files are all members of the Berkeley DB lineage of key value stores. default/ feels like it’s also a key value store but one suspects that one could probably put a command in there and something would execute it. rc.d is 99% code but with semantics in the symlinks too (see also Debian’s alternatives.) A very large number of files look like braced C code; named.conf even requires terminal semicolons! There’s no value in either consistency or diversity of the underlying implementation be it a registry — the registry, or a gconf thing — or a filesystem smorgasbord of config languages. Without the discipline (authoritarianism?) of a social structure — for example a “company” with a hierarchical leadership that can promote/fire you — you will get diversity in any system. I just reminded myself of the time I used ansible YAML Jinja templates to control EdgeRouter config files that programmatically built config in /etc. Time for a leisurely stroll in a real garden I think, far away from a computer.
