This can be enabled as available with the --reflink=auto flag for cp. When copying between different filesystems it still makes sense to add the --sparse=auto

This can be enabled as available with the --reflink=auto flag for cp. When copying between different filesystems it still makes sense to add the --sparse=auto flag to keep a copy of a sparse file sparse, too. My alias for cp is: cp -i --reflink=auto --sparse=auto
