Presently if you want to perform a sparse checkout, you must either do a full clone and then recheckout, or do a git init, manually set up sparse, and then fetch and checkout.
This patch implements easily accessible sparse checkouts during clone, in the --sparse-checkout option.
$ git clone REPO --sparse-checkout PATH
