I expect that (he?) wants to have the process be more-or-less fully
automated - i.e., have the mouting and whatever else is necessary for
the installer to recognize and use the (externally located) preseed file
be handled automatically, preferably without even needing to explicitly
specify the preseed-file location at install time.
Assuming the initrd used in the installer environment is customizable /
tweakable, this shouldn't be impossible, but I'd have to do some
research to figure out how to go about it. (Worst-case scenario, you
might have to do a custom build of d-i...)
