 I don't think I understand what you mean by manage here.  You can't
 prevent users from running 'ldconfig'.  If you run 'ldconfig' it will
 read the sonames and place symlinks to the "newer versions" of the
 library.

 It doesn't.  It parses the soname, it's not quite the same.  And I said
 "dynamic linker" not "ldconfig".  The dynamic linker does not know
 about version numbers.
