From: Derrick Stolee <redacted> The 'git init' command creates the ".git/info" directory and fills it with some default files. However, 'git worktree add' does not create the info directory for that worktree. This causes a problem when running "git sparse-checkout init" inside a worktree. While care was taken to allow the sparse-checkout config to be specific to a worktree, this initialization was untested. Safely create the leading directories for the sparse-checkout file. This is the safest thing to do even without worktrees, as a user could delete their ".git/info" directory and expect Git to recover safely.
