Thanks for the patch. But I do not think that should be a good idea to
change the defaults. Maybe for your case can be a good idea to make
another custom.fs.sfs for this structure, and use a custom mke2fs.conf.

I guess XFS will fit much better for your case, with defaults.

Warning: the patch introduced a cosmethical change, that I want to keep.
