I currently use genext2fs, followed by tune2fs to add the journal and
e2fsck to fix the incorrect FS version number. But it's extremely
inefficient, especially since genext2fs first builds the filesystem in
memory before committing to the output image. Not good when you want to
create a 500GB partition :-)
