Do you mean that the generated script.sh ends up in your home dir?
It is expected since default-directory in your buffer is "~/":

>   (dired "~/")
>   (make-indirect-buffer "tmp.org" "tmp-indirect")

Note that you called make-indirect-buffer without third argument.

According to manual:

> (make-indirect-buffer BASE-BUFFER NAME &optional CLONE)
> CLONE nil means the indirect buffer's state is reset to default values.

No surprise you got your file in the default-directory (~/).

If you use (make-indirect-buffer "tmp.org" "tmp-indirect" t) instead,
the script.sh link will be relative, as expected.

Let me know if I miss something.

Best,
Ihor
