Hi all,
This is something I've wanted to see for a very long time, and it
finally occurred to me that perhaps I should say something about it!
It would be a very nice thing to have a flag to e2fsck, presumably -z,
to zero out any unused data blocks, inodes and so on. The goal is to
minimize the amount of space required after compressing a virtual disk
image or similar, and to make sure any non-data isn't lying around.
