Is a spec for a very simple approach to online defrag that I hope we can
implement in the near future. I think that once we have the mechanisms
to freeze clusters and to swap clusters, implementing much more
sophisticated defragmentation algorithms will become easy.
This image defragmentation might in fact cause even more fragmentation
at the filesystem layer.
That's a good point. Is there a reasonable way to do this cooperatively
with the underlying filesystem?
BTW, the same problem would occur for sparse file system images, no?
