A zsh user may have set `ZDOTDIR` to something other than `$HOME`, in which case the profile and rc files will not be located under `$HOME`. But unless the system `zshenv` has done something unusual, it is usually a safe bet that there will be a `$HOME/.zshenv` that, if nothing else, will be setting up `ZDOTDIR`.
