Hi,

It is not because it is well-documented that I do not feel confused or
it puzzles me or how difficult it is to understand or know about,
especially when the definition appears now a bit awkward.  Ah it is the
meaning from the dictionary of mystery. ;-)

Kidding aside, thanks for the explanations.  I have bookmarked them.

Naively and what confuse me is the redundancy of the information.  For
example, is it possible to do something else than “gnu”?  Or when one
thing is fixed, other parameters are also fixed, for instance does it
make sense

        "x86_64-linux-gnu"    
        "i686-hurd"        
        "arm"               
        "ld-hurd-arm.so.2"

?

Obviously, the plumbing where it is not a “mystery” for some user is
necessary.  But for user like me, the interface should be simple.

Yes.

I agree.  Aside my usual drift. ;-)


All the best,
