OK, say we view it as "read only", except for the editor
(note "the editor" might be "vi", so you can't complain 8-)).

How is path-to-file + path-to-key-in-file any different
than absolute-path-to-key?

The only thing that seems different is the implied component
seperator at the file/file-content boundary, and the
translation of the "_" into the file space component
seperator, and back.

It's all just a matter of represntational geometry for the
same information, isn't it?

"vi"?  "sed"?  "any text editor"?

The lack of constraints on how one may interact with the rc.conf
is one of its main weaknesses.  A single missing quotation mark
will result in an inaccessible system, if you don't have console
access, and one that must be repaired, if you do.

There's not even a "virc" equivalent to "vipw", that can do a
consistency check on the file to make sure it's "sourceable" by
a shell script, before permitting the edits to replace the valid
contents, and keep a backup of the previous file for you.

Alternately, we can just call a spade a spade, and admit that
what we have is a flat file registry, which pretends to be
hierarchical by using "_" as a hierachy delimiter for component

Actually, this is a lot like the Manx subdirectory support in
the shell program that came with the developement environment,
and used "topdir/subdir/finaldir" as the name of the directory,
and simply hid the names of all but the last component.  8-).
