/etc/default/* key=value files were first used
in M$ XENIX. (_Not_ SCO XENIX, but M$ XENIX.)
Strange, but true. (I distinctly recall some
Usenet postings, from the XENIX group at M$ at
the time, discussing the feature.)
I presume they migrated into mainstream Unix (and
eventually Linux) since XENIX was one of the inputs
into the SV(r4?) de facto standardisation, back in
the days of the Unix Wars. (And _that_ is why some
parts of the Unix source have an M$ copyright (plus
many other copyrights).) Solaris is Sun's SVr4(?),
which is _probably_ how Solaris got /etc/default/*.
Of course, the idea of Bourne-ish shell readable
key=value "scripts" preceeded that. Interestingly,
the original M$ stuff was a C API and the files
were usually(?) not parsed/processed by the shell.
This is why some of the older /etc/default/* files
are not usable by the shell; and also why some of
the programs they are for (e.g., tar(1)) cannot
(could not?) be parsed as shell scripts.
I first saw /etc/default/* a long long time ago,
c.1985 or so? On, if I am recalling correctly,
M$? XENIX for the Apple Lisa (maintenance and sales
of that XENIX port was later taken over by SCO).
Anyone remember the Apple Lisa? (Which was later,
and very briefly, called something like the Apple
