Side note: I really don't see how your argument of "XFS has been able
to do something like this for over a decade, using an even uglier
trick that is hidden and not documented" is at all an argument for
You're saying "nobody else should be doing what I've been doing for a
long time", and backing that argument up with "but I don't document
it, and it's completely different because it's done at mkfs/debugfs
time rather than mount-time".
But now that people are talking about a filesystem-independent way of
doing the same thing, now it's suddenly poisonous.
Dave, I call BS on your arguments. Or maybe I misunderstood it. But it
does smell very "do what I say, not what I do".
