  This is definitely a move in the right direction. I'd be even happier
if e2fsck would write quota file directly - then we could just make
quota files hidden inodes, start doing quota accounting immediately
on mount and always do quota journaling. That would save us quite some
trouble in kernel. The only problem with this is that we'd need to pull
knowledge about quota formats in e2fsck...
