    I wasn't concerned so much with security, but with user experience.
    For instance, some editors don't perform fsync-then-rename, but simply
    truncate the file when saving (because they want to preserve hard
    links). With XFS, this tends to cause null bytes on crashes. Since
    ext3 has got a much larger install base, this would result in lots of
    bug reports, I fear.

    Without zeroing, the truncating editor might garble the file in a more
    obvious way, but you've got the security issue (and I agree that this
    is more of a PR issue).
