I have a number of systems I support and some are Arch Linux and some are Debian or Debian derivatives. I recently saw a question about the hostname command and the difference between the -i and -I options. To my surprise, the version of hostname from Arch did not have the -I option. Looking at versions, Arch had v1.94 from GNU's inetutils, but my Debian systems had version 3.19 or 3.20. My questions are:
Where did these versions fork?
Does Debian have its on versions of many other utilities?
Is there some other tree from which Debian's utilities are derived?
Just curious.
