Why zshrc rather than zshenv?  The wrong ~/.zshenv will be loaded if $HOME 
is not set correctly before the end of the global zshenv.

Using `id -un` there, particularly twice, should not be necessary.  E.g.,

  if (( EUID == 0 )); then
     export HOME=/root
  else
     export HOME=/home/$LOGNAME
  fi

So whether HOME is set correctly (before executing the above snippet) has 
nothing to do with whether the current directory is "/" ?  I would expect 
the two conditions to be related, e.g.,

  if [[ -z "$HOME" || "$HOME" == "/" ]] ; then
     # ... export $HOME correctly, then ...
     cd
  fi

Or is there some reason you don't want to have the "cd" in the global 
config?

How about something like

   if [[ -z "$ALREADY_DID_CD_HOME" ]]; then
      export ALREADY_DID_CD_HOME=$HOME
      cd
   fi
