Answer 1

This got me thinking, since I would like very much the solution of using a symlinked file/dir but am stuck on a windows computer. As far as I know the symlinks in windows doesnt really work in the same way. So another solution could be to write two scripts/bash functions to "import" and "export" the file(s) in question, such as:

import() {
    cp -fr /home/some/directory /htdocs/
}

export() {
    cp -fr /htdocs/directory /home/some/
}

Then you would have a copy of the file in your repository, which you could git add.
