mkfs is missing the -d option needed for copyin files

Build failed with exit code 4
The buildroot was: /var/tmp/build-root-ej/openSUSE_Factory-x86_64/.mount

Cleaning the build root may fix the problem or allow you to start debugging from a well-defined state:
  - add '--clean' option to your 'osc build' command
  - run 'osc wipe [--vm-type=...]' prior running your 'osc build' command again

Uh, mkfs does not even have -d (according to man mkfs). "copy(-)in" is also a term I would (only) associate with cpio rather than mkfs. But I have a hunch...

So I think build.rpm needs a dependency on e2fsprogs / mkfs.ext4.
