Stack install does its thing in some hashed directory under .stack-work by default,

but I want to write to <package-root>/bin as part of the configure process. I'm trying

to do this as follows:

-- configure file contains:

cd $(stack path --project-root)

echo "..." > .bin/foo.sh

cd -

> cd <project-root>

> stack install

I'm doing this under Windows with the born shell in my path.

Problem: the use of stack to find the project-root directory is blocked waiting for

the outer stack to terminate! This may have something to do with Windows

"Device or resource busy" lock.

Is there a better way?

Thanks,

Dominick
