I had in fact the answer, a long time ago: because they simply do not
know that ed(1) exists, and sed(1) etc.
A group, providing an ISDN router based on Debian, was requiring a lot
of memory and disk space. I asked why??? that much for _that_?!! The
answer: we need perl(1) installed. But what for? Answer: to replace
@@GATEWAY@@ and so on by customized values in a file... (They didn't
even thought of building a distribution on a vulcan to simply install on
the target.)
They didn't know about ed(1). So I tell them regexp were ed(1); and
ed(1) was required by POSIX.2. And tried to make the demonstration... to
see that Debian didn't provide ed(1) by default. I ask Debian, why the
f...?!!? Answer: GNU's Not Unix...
And this day I realized I was not GNU. And switch to *BSD before asking
myself some questions that lead me to Plan9...
