Here's the description for "-d root-directory|tarball" from the mkfs.ext4 man page:

"Copy the contents of the given directory or tarball into the root directory of the file system. Tarball input is only available if mke2fs was compiled with libarchive support enabled and if the libarchive shared library is available at run-time. The special value "-" will read a tarball from standard input."
