In-Reply-To: <pull.2478.git.git.1793530936.gitgitgadget@gmail.com>

From: Harald Nordgren <haraldnordgren@gmail.com>

When replacing `dirname`, elevation is required, otherwise the command will fail with:

  + ln -sfT /usr/bin/gnudirname /usr/bin/dirname
  ln: failed to create symbolic link '/usr/bin/dirname': Already exists

as observed in https://github.com/git-for-windows/git/actions/runs/40223871341/job/121274294974?pr=6473#step:3:909
