*Definitely* *not*! The smaller the machine, the more efficient
the code should be. And having an interpreter as yet another layer
of complexity (besides the C library) between the kernel and the
PID1 program is contra-productive in this regard. And, BTW, your
Script in it's current form is still missing some essential features
(i.e. setsid, setpgid) to make it actually work as intended.
And no, it is not a good idea to delegate that task to the exec'ed
program (I leave it as an exercise for the reader to find out why).
And yes, I will continue to point out errors and debunk misconceptions
in your posts, for the benefit of the elusive "innocent reader" of
DNG.

As for the educational value: I fail to see what good does learning
things already proven wrong.

Correct, in that it represents a superficial and wrong and view, and
it paints a warped picture of the things *actually* happening.

If 16 lines of C pose a mystery, one should look for another hobby.
Or get a clue already.
