Description

This would improve layered image performance, and enable quick, conservative usage for an image. It should be possible to add to an existing format 2 image.

History

#1 Updated by Alex Elder over 7 years ago

I was thinking this weekend of creating this issue exactly.

Are you envisioning keeping these with the image header?

Even without it I could keep an internal bitmap of what
exists in the kernel client, at least until a flatten
operation is detected.

Also, I wonder at what point it becomes worthwhile to
use something different from bitmaps (such as extents
that define entire ranges of existent or non-existent
objects).
