The list is, of course, spurious.

$ cat /etc/debian_version

$ apt-cache rdepends libsystemd0 | wc -l

Even worse, this whole thread in d-u/d-d is based on a total misunderstanding by
LKCL of what libsystemd0 *is*.

It's a library whose sole purpose is to make sure that packages *don't* depend on
systemd.

Every single function in libsystemd0 looks like:

  if (init_is_systemd) {
    do some systemd stuff;
  }
  else {
    carry on as before;
  }

But LKCL decided that the problem was not systemd as init, it was the presence
of packages containing the letters d, e, m, s, t and y in one particular order.
