It's not known, at least not to me. I know that you cannot
mount an image that is _on_ an affs partition via loopback.
(Due to the lack of a bmap() in affs). But you should be able
to mount an affs image that is on some other partition fine.
The affs in the 2.1.xx kernel has several bug fixes and
other improvements; alas, it's not that simple to bring the
'stable' version up to that (I did this around 2.1.3x, but
it hasn't made it into 2.0.xx).
> Btw, mount -t affs image.adf /mnt -o loop works fine.
Since I don't know the difference between the two methods
as far as the fs is concerned, I can't comment.
Hopefully, I will have a new affs within the next, say 10, days.
Then I could make another effort to update the 2.0 version, too.
