 Yes, that would work.

 An other place we should patch is the `maketar` function in `lib/RBM.pm`,
 which is used to generate the source tarballs:
 {{{
 diff --git a/lib/RBM.pm b/lib/RBM.pm
 index 75912af..087ebe3 100644
 --- a/lib/RBM.pm
 +++ b/lib/RBM.pm

      }
      my %compress = (
          xz  => ['xz', '-f'],
 -        gz  => ['gzip', '-f'],
 +        gz  => ['gzip', '--no-name', '-f'],
          bz2 => ['bzip2', '-f'],
      );
      if (my $c = project_config($project, 'compress_tar', $options)) {
