Well... yes.  That's probably a bit unfortunate.  The current mechanism
always creates a couple of directories if they don't already exist:

  /bin
  /home
  /etc
  /lib
  /tmp
  /usr
  /usr/bin
  /usr/lib
  /usr/src
  /usr/local
  /usr/local/bin
  /usr/local/etc
  /usr/local/lib
  /usr/tmp
  /var/log
  /var/run
  /var/tmp

If the directory couldn't be created because a non-directory file uses
the same name, it deletes that file and tries to create the directory
again.  It's not perfect, but at least we know that the directories
exist, afterwards.  We could add a mode which drops the aggressive
creation strategy, but I only see that *could* make sense for home.

Nothing "magic", it's just the current state of affairs.  Creating a
/home mount point is certainly a good workaround, and it should even be
a bit faster than a symlink.
